1 This is FET version 5.45.1
4 Program description:
6 FET is free timetabling software (licensed under the GNU Affero General Public License version 3 or later).
7 This program aims to automatically generate the timetable of a school, high-school or university.
8 It may be used for other timetabling purposes.
10 FET can mean "Free Educational Timetabling" (the "E" in the middle may also stand for other words, based on your personal preference).
12 FET homepage: https://lalescu.ro/liviu/fet/
17 FET is created in the following environment: openSUSE Tumbleweed GNU/Linux distribution, Linux 5.7.5, Xfce 4.14,
18 Xfce Terminal Emulator 0.8.9.2, Midnight Commander 4.8.24, Kate 20.04.1, KDiff3 0.9.98, grep 3.4, sed 4.8,
19 Qt 5.15.0, Qt Creator 4.12.1, gcc 10.1.1, g++ 10.1.1, make 4.3, gdb 8.3.1, Valgrind 3.15.0, Coverity Scan 2019.03,
20 Cppcheck 2.1, SpeedCrunch 0.12, Inkscape 1.0, GIMP 2.10.18, ImageMagick 7.0.10, tar 1.32, gzip 1.10, bzip2 1.0.8,
21 other great software (most of them are free software, in the sense defined by The Free Software Foundation).
23 The executable version of FET for Windows is obtained in the following environment: Windows 10 operating system,
24 Command Prompt, Total Commander 9.51, Notepad, Python 2.7.18, Qt 5.15.0, Qt Creator 4.12.1, MinGW 8.1.0, 7-Zip 19.00.
26 FET is a C++ application and uses Qt, a C++ toolkit for cross-platform application development.
27 FET can be run on any platform supported by Qt (GNU/Linux, Windows, Mac OS X, and maybe others).
29 You will need a C++11 compliant C++ compiler to compile FET.
31 GNU/Linux, Mac OS X:
32 For running, you need only the archive of FET compiled for your operating system (which contains the necessary libraries).
33 For compiling, you will need this software:
34 make 4.2.1 or similar (GNU Make).
35 gcc 10.1.1 or similar.
36 g++ 10.1.1 or similar (or gcc-g++, or gcc-c++, the name may vary. This program may be included in the gcc package).
37 Qt 5.15.0 or compatible (The authors also tried to maintain backwards source compatibility with Qt 4.v.v).
39 Note: You need a C++11 compliant C++ compiler. You might be able to use the Clang C++ compiler or other C++ compiler instead of gcc and g++.
42 For running, you need only the archive of FET compiled for Windows (which contains the necessary dll-s).
43 For compiling, you need Qt and a compatible C++ compiler complying with the C++11 standard (MinGW is a possibility).
48 You can download the latest version from the FET homepage, https://lalescu.ro/liviu/fet/
51 Getting - compiling - installing the GNU tools: make, gcc and g++ (or gcc-g++, or gcc-c++):
53 GNU/Linux, maybe Mac OS X: Most probably, your platform has these installed by default or available on the internet
54 as precompiled packages. If you don't have them, please install them using YaST (on openSUSE), Adept Manager
55 (on Ubuntu) or other package manager.
56 To verify that you have the correct packages, write "make --version", "gcc --version" and
57 "g++ --version".
58 Advice from a user on Ubuntu: "sudo apt-get install build-essential" installs build libraries commonly used.
60 Maybe Mac OS X from a user: Install Xcode (current version is 7.3.1) from the Mac App Store.
61 (Once installed, I think you'll need to open the Xcode app to finish the installation.)
63 Windows: you need a Qt compatible C++ compiler.
64 Maybe an easy option is the MinGW compiler, available optionally with the Qt distribution or on the Qt download page.
65 (You might also download MinGW from the internet. There might be more variants. One of them is on: http://mingw-w64.org/)
68 Getting - compiling - installing Qt:
70 Qt homepage: https://www.qt.io/
72 You will need Qt 5.15.0 or compatible to compile FET (The authors also tried to maintain backwards source compatibility with Qt 4.v.v).
73 You can get the corresponding version of Qt with your package manager or from the internet (preferably from the Qt homepage).
74 Qt can be used with the GNU (L)GPL or commercial license (The authors chose the GNU (L)GPL license).
76 GNU/Linux: It is possible to use YaST (or Adept Manager) or other package managers to get your version of Qt, pre-compiled.
77 Or you can download, (possibly) compile and install Qt from the internet (preferably from its homepage).
78 A possible name for the precompiled package is libqt5.
79 A user reported that on Ubuntu "sudo apt-get install qt5-default" without quotes should work.
81 Windows - Download latest Qt from the internet (preferably from its homepage). There are available precompiled packages, but the authors chose
82 to compile Qt from the sources using the additional configure option "-schannel". This is done to ensure that SSL will work in FET using the
83 available SSL dll-s from Windows. For a faster Qt configuration, the authors download/compile/install only the qtbase component,
84 with a configure command which might look like:
85 "configure.bat -opensource -confirm-license -platform win32-g++ -schannel -opengl desktop -release -nomake examples -nomake tests".
86 (When we tried to use the recommended option "-opengl dynamic" we got a compiler error.)
87 Note that to be able to open ui files with Qt Designer or ts files with Qt Linguist you need to install the Qt component qttools
88 (or the whole Qt package).
90 Mac OS X:
91 Maybe you can get pre-compiled Qt packages for Mac OS X. If not, get Qt from the internet (preferably from its homepage).
93 Note about the Qt "QMAKESPEC" variable: advanced topic, read this if you get Qt errors about the environment not being set, or environment
94 variable QMAKESPEC not being set, or if the Qt environment is not set correctly: Qt needs to know the environment you are using. It is usually
95 something like: linux-g++, macx-g++ or win32-g++ (platform-compiler). You can find all the supported platforms in the directory "mkspecs" of Qt
96 (some usual locations are /usr/share/qt5/mkspecs or /usr/lib/qt5/mkspecs on GNU/Linux or C:\Qt\5.15.0\mkspecs on Windows).
97 It seems that Qt automatically finds the platform (there is a default configuration in the "default" subdirectory of the "mkspecs" directory,
98 which is created automatically when you install Qt). If the default configuration is not working or is wrong, you may need to set the
99 correct QMAKESPEC variable for your platform. Under Windows, you can create an environment variable QMAKESPEC equal to win32-g++
100 (if you are using MinGW), under other platforms create an environment variable named QMAKESPEC equal with the correct platform-compiler
101 you are working on (for instance macx-g++ or linux-g++).
104 Compiling FET:
106 You will need a C++11 compliant C++ compiler to compile FET.
108 Note: if after unpacking the tar.bz2 sources archive you obtain some files with incomplete/truncated file names in the sources directories,
109 you might need to use a better (un)packer (probably a recent version of the official tar and bzip2 should be fine).
110 For GNU/Linux and maybe Mac OS X, "tar -jxvf fet-v.v.v.tar.bz2" should work correctly.
111 For Windows, either use a modern good (un)packer, or, advice from a user:
112 1. download mingw-get-setup.exe from https://sourceforge.net/projects/mingw/files/
113 2. run mingw-get-setup.exe
114 3. check msys-base to be installed, Apply Changes from Installation menu and close MinGW Installation Manager
115 4. run C:\MinGW\msys\1.0\msys.bat
116 5. $ cd to the directory where the .tar.bz2 file is
117 6. $ tar -jxvf fet-v.v.v.bz2
119 Note2: compilation takes long (maybe even 1 hour, if you are using an older computer). The file
120 rules.cpp takes the longest time to compile, maybe even 1 minute or more.
122 Note3: the following situation may appear under GNU/Linux, but it could be met also on other platforms.
123 Depending on your Qt installation, it may happen that the FET intermediary files and executables are very large (~100 MB for the fet executable
124 instead of ~10 MB). It is not sure if this affects the FET speed and performance, but anyway it is unpleasant. In this case, you may want to
125 modify some files in your system (Qt files) to improve this. You need to change some Qt configuration files and recompile FET from the beginning
126 (remove any temporary files with make distclean or unpack FET sources again, in an empty location).
127 Notations: mkspecs is a directory and QMAKE_CFLAGS_RELEASE and QMAKE_CXXFLAGS_RELEASE are two sections (text on two lines) contained in a file
128 in a subdirectory of mkspecs (some possible location for these are given in this paragraph, shortly below).
129 If mkspecs files for your platform contain the -g flag (text) in the QMAKE_CFLAGS_RELEASE or QMAKE_CXXFLAGS_RELEASE sections, you need to remove
130 this flag. If they do not contain -g flag in these sections, then you don't need to remove anything (and most probably the intermediary files and fet
131 executable will have normal size).
132 More details about where can you find the mkspecs files: under openSUSE GNU/Linux, it seems that for newer versions of Qt (>=4.7.1), the problem
133 is no longer present. In the past, the location of this minor problem was in the file /usr/share/qt5/mkspecs/common/g++.conf, at lines 10 and 25,
134 you needed to remove the "-g" flag from the QMAKE_CFLAGS_RELEASE and QMAKE_CXXFLAGS_RELEASE sections (root access needed to make this change).
135 Under Fedora GNU/Linux for the same problem, a user reported that you need to modify /usr/lib/qt4/mkspecs/common/g++.conf
136 and /usr/lib/qt4/mkspecs/linux-g++/qmake.conf (remove the -g flag from QMAKE_CFLAGS_RELEASE and QMAKE_CXXFLAGS_RELEASE sections).
137 (The mkspecs directory contains more subdirectories, in the form platform-compiler, you need to search for your corresponding directories/files.
138 For instance, GNU/Linux with gcc compiler is named "linux-g++", and you may also need to modify the "common" section).
139 Another solution, by another user: the addition of the lines
140 "linux-g++*: QMAKE_CXXFLAGS_RELEASE -= -g"
142 "linux-g++*: QMAKE_CFLAGS_RELEASE -= -g"
143 (without quotes) in the files src/src.pro and src/src-cl.pro (you can add them at the end of these files, or in another proper location).
145 Note NMkJobs: advice from a user: if you have a multiple core computer, you may be able to split the compilation into more threads, with the -j option for the
146 make command, so that the compilation is faster. This option creates a number of compilation threads equal with the number specified along with the -j option.
147 Under GNU/Linux or Mac OS X, just write "make -j 2" if you have dual core or "make -j 4" if you have quad core (in case you have quad core and you want
148 to keep a core free for other tasks, write "make -j 3"). This is proven to work under GNU/Linux and Mac OS X. Under Windows it depends on the C++ compiler (you
149 may try it to see if it works).
151 Currently FET can be compiled with a C++ compiler, using Qt version 5.15.0 or compatible.
153 Note NUseSystemLocale: If you want FET to autodetect the system locale language, type <<qmake fet.pro "DEFINES+=USE_SYSTEM_LOCALE">>
154 or simply <<qmake "DEFINES+=USE_SYSTEM_LOCALE">>. This will work if you recompile from the beginning all the FET package (remove
155 all the intermediary files and recompile), and also if you did not use FET on this machine or if you remove the settings file/registry entry for FET
156 (otherwise FET will retain the language which was already saved in its settings).
158 Note4: If you get an error like this:
159 In file included from ../../Qt5.3.2/5.3/gcc_64/include/QtGui/qopenglcontext.h:62:0,
160 from ../../Qt5.3.2/5.3/gcc_64/include/QtGui/QtGui:32,
161 from ../../Qt5.3.2/5.3/gcc_64/include/QtWidgets/QtWidgetsDepends:3,
162 from ../../Qt5.3.2/5.3/gcc_64/include/QtWidgets/QtWidgets:3,
163 from engine/import.cpp:35:
164 ../../Qt5.3.2/5.3/gcc_64/include/QtGui/qopengl.h:110:21: fatal error: GL/gl.h: No such file or directory
165 # include <GL/gl.h>
167 compilation terminated.
168 you may need to install additional packages before compiling FET. For instance, under openSUSE GNU/Linux you may need to install Mesa-devel.
169 As reported by a user, on Mint GNU/Linux he needed to install mesa-common-dev and libgl1-mesa-dev.
171 Note 5: If you only want to compile the command-line version, open the file fet.pro with a text editor and from the second line remove the
172 text "src/src.pro ".
176 - You will need Qt 5.15.0 or compatible to compile this program.
177 - type "qmake fet.pro" or simply "qmake". You have to use qmake from Qt 5 series, which on some systems
178 might be named qmake-qt5 (this command is executed very fast, so don't worry if you get immediate return from it)
179 See also notes NUseSystemLocale and Note4 above.
180 - type "make" (this takes a long time, maybe even 1 hour). See also note NMkJobs above.
181 To remove the compiled objects/executable: "make clean" and/or "make distclean".
184 Mac OS X:
185 3 Variants:
187 1. First variant, if you use the gcc compiler:
188 - You will need Qt 5.15.0 or compatible to compile this program.
189 - type "qmake fet.pro" or simply "qmake". You have to use qmake from Qt 5 series.
190 (this command is executed very fast, so don't worry if you get immediate return from it)
191 - IMPORTANT: you might need to write: "qmake -spec macx-g++ fet.pro", if "qmake fet.pro"
192 does not produce a correct makefile.
193 See also notes NUseSystemLocale and Note4 above.
194 - type "make" (this takes a long time, maybe even 1 hour). See also note NMkJobs above.
195 To remove the compiled objects/executable: "make clean" and/or "make distclean".
197 2. Another variant:
198 - Type "qmake fet.pro" and then "xcodebuild".
200 3. Another variant, if you use the Clang C++ compiler (which seems to be the default for Qt 5.15.0 on Mac):
201 It seems that you need to type:
202 "/Users/Yourname/Qt5.15.0/5.15.0/clang_64/bin/qmake -r -spec /Users/Yourname/Qt5.15.0/5.15.0/clang_64/mkspecs/macx-clang", then "make"
203 (the -r parameter might not be necessary.)
204 Please see: https://lalescu.ro/liviu/fet/forum/index.php?topic=2488.msg13425#msg13425 (and also see the whole topic there.)
207 Windows: MinGW C++ compiler: you need Qt 5.15.0 or compatible, and MinGW.
208 You might use other C++ compilers if you want, please see the Qt documentation.
209 for other variants. Any C++ compiler that supports Qt should be good.
210 You need to run "qmake fet.pro" or "qmake" (this command is executed very fast, so don't worry if you get
211 immediate return from it) and then, if you are using MinGW, "mingw32-make" (this takes a long time, maybe even 1 hour)
212 in a command line in the FET directory.
213 See also note NUseSystemLocale above.
214 See also Note4 above.
215 See also note NMkJobs above.
216 (You can use the command line prompt of Windows or the Qt command line prompt shortcut in the Qt shortcuts menu.)
217 Then, you can remove the directories "src" and "tmp", to save up space, if you want.
218 You will need to copy the dll-s in the same directories as in the official FET archive for Windows.
221 Installing FET:
223 GNU/Linux, and maybe Mac OS X:
224 Type "make install" with root permissions.
226 Mac OS X: A user reported that one can obtain a universal Mac OS X executable with:
227 $ cd /"pathto"/Qt/5.5/clang_64/bin/
228 $ ./macdeployqt /"pathto"/fet.app
229 (with Qt 5.5)
232 Move the FET directory to a place of your choice.
235 Running FET:
236 Note: The FET main window contains a menu with the items: File, Data, Statistics, Advanced,
237 Timetable, Settings, Help. Everything is right if you have that. Optionally, on the main window there may be a toolbox
238 containing shortcuts (if selected by the user in the settings. By default it is selected).
240 To run FET in interface mode, you just need to run the executable named fet or fet.exe.
242 GNU/Linux, and maybe Mac OS X:
243 chdir to the directory where the fet executable is (for instance, "cd ~/fet-v.v.v/") and run it with "./fet" or with the suitable command
244 for your platform. Alternatively, you may run the executable named fet from the fet-v.v.v directory, using another method. The fet executable
245 will be located inside the fet-v.v.v directory after a successful compilation.
247 Note for Mac OS X about using translations (if you want to run FET into other language): it seems that you need to copy the contents
248 of the "translations/" directory into the directory fet-v.v.v/fet.app/Contents/MacOS/translations/ or into the directory /usr/share/fet/translations/
249 (if you compiled/installed FET by yourself). Or copy the whole directory translations/ into fet-v.v.v/fet.app/Contents/MacOS/ or into usr/share/fet/
250 More notes for the Mac OS X platform, from a user: copying the translations/ directory into the directory fet.app/Contents/MacOS/ is
251 possible from the command line in X11 xterm (but it is not possible with the finder program, because the file extension ".app" is
252 exclusive for applications, so the program finder interprets a directory with the extension ".app" as an application).
255 Run the executable fet.exe (its location is inside the fet-v.v.v directory, you can find it there if you have FET precompiled for Windows or after you compiled it).
257 Command line version usage: fet-cl --inputfile=FILE [other options]
258 FILE is the input file, for instance "data.fet"
260 Other options are:
263 DIR is the path to results directory, without trailing slash or backslash (default is current working path). Make sure you have write
264 permissions there.
267 TLS is an integer representing the time limit, in seconds, after which the program will stop the generation (default 2000000000, which is
268 practically infinite).
271 LEVEL is an integer from 0 to 7 and represents the detail level for the generated HTML timetables (default 2, larger values have more
272 details/facilities and larger file sizes).
275 LANG is one of: ar, ca, cs, da, de, el, en_GB, en_US, es, eu, fa, fr, gl, he, hu, id, it, ja, lt, mk, ms, nl, pl, pt_BR, ro, ru, si, sk,
276 sq, sr, tr, uk, uz, vi, zh_CN, zh_TW (default en_US).
294 WT1 to WT16 are either true or false and represent whether you want the corresponding timetables to be written on the disk (default true).
297 PAT is either true or false and represets if you want activity tags to be present in the final HTML timetables (default true).
300 PNA is either true or false and represents if you want -x- (for true) or --- (for false) in the generated timetables for the not available
301 slots (default true).
304 PB is either true or false and represents if you want -X- (for true) or --- (for false) in the generated timetables for the break slots
305 (default true).
308 DTAD is either true or false, represents if you want the HTML timetables with time-axis divided by days (default false).
311 DVH is either true or false, represents if you want the HTML timetables to duplicate vertical headers to the right of the tables, for
312 easier reading (default false).
315 PSA is either true or false, represents if you want the HTML timetables to show related activities which have constraints with same
316 starting time (default false). (for instance, if A1 (T1, G1) and A2 (T2, G2) have constraint activities same starting time, then in T1's
317 timetable will appear also A2, at the same slot as A1).
319 --randomseeds10=s10 --randomseeds11=s11 --randomseeds12=s12 --randomseeds20=s20 --randomseeds21=s21 --randomseeds22=s22
320 where you need to specify all the 6 random seed components, and s10, s11, and s12 are integers from minimum 0 to maximum 4294967086,
321 not all 3 zero, and s20, s21, and s22 are integers from minimum 0 to maximum 4294944442, not all 3 zero (you can get the same timetable
322 if the input file is identical, if the FET version is the same (or if the generation algorithm did not change), and if all the 6 random seed
323 components are respectively equal).
326 WNP is either true or false, represents whether you want a message box to be shown, with a warning, if the input file contains not perfect
327 constraints (activity tag max hours daily or students max gaps per day) (default true).
330 SMHDAEDP is either true or false, represents whether you want a message box to be shown, with a warning, if the input file contains nonstandard
331 constraints students min hours daily with allow empty days (default true).
334 WGA is either true or false, represents whether you want a message box to be shown, with a warning, if the input file contains nonstandard
335 timetable generation options to group activities in the initial order (default true).
338 WSSA is either true or false, represents whether you want a message box to be show, with a warning, if your input file contains subgroups
339 which have the same activities (default true).
342 PDT is either true or false, represents whether you want to show the detailed (true) or less detailed (false) years and groups timetables (default true).
345 PDTFP is either true or false, represents whether you want to show the detailed (true) or less detailed (false) teachers free periods
346 timetables (default true).
349 ECSV is either true or false, represents whether you want to export the CSV file and timetables (default false).
352 OCSV is either true or false, represents whether you want to overwrite old CSV files, if they exist (default false).
355 FLHCSV is either true or false, represents whether you want the heading of the CSV files to be header (true) or data (false). The default
356 value is true.
359 QCSV is one value from the set [doublequotes|singlequotes|none] (write a single value from these three exactly as it is written here).
360 The default value is doublequotes.
363 FSCSV is one value from the set [comma|semicolon|verticalbar] (write a single value from these three exactly as it is written here).
364 The default value is comma.
367 SVR is either true or false, represents whether you want to show virtual rooms in the timetables (default false).
370 WANFTFS is either true or false, represents whether you want the program to issue a warning if you are using activites which are not
371 fixed in time, but are fixed in space in a virtual room, specifying also the real rooms (which is not recommended) (default true).
374 VBS is either true or false, represents whether you want additional generation messages and other messages to be shown on the command
375 line (default false).
377 Run "fet-cl --help" to get usage information.
379 Run "fet-cl --version" to get version information.
381 You can ask the FET command line process to stop the timetable generation, by sending it the SIGTERM (or SIGBREAK, on Windows) signal. FET will then
382 write the current timetable and the highest stage timetable and exit. (If you send the FET command line the SIGINT signal it will stop immediately,
383 without writing the timetable.)
385 The result of the operation is logged in the file outputdir/logs/result.txt.
387 Also, you have in logs the initial order of activities and a list of maximum placed number of activities. If your timetable is impossible, say it stops
388 at maximum n placed activities, look at the n+1-st activity in the initial order, for it or its students/teachers may be the problem.
390 For the command line version, probably the most useful output to use internally in an application might be the activities_timetable.xml.
391 You have of course also the xml timetables for students and teachers and the nicely formatted HTML timetables to present directly.
393 You'll get a console output to help you with data, along with the files in the directory outputdir/logs/.
395 If you are a programmer, in the file src/engine/messageboxes.cpp you'll find the implementation of the various messages. You
396 can modify these functions, catching them in your program. Also, you can catch the end of the program (successful or unsuccessful) in
397 the file src/interface/fet.cpp, in the command-line code part.
399 If you want to be completely independent from Qt, using only standard C++, you can remove all the Qt includes and
400 reimplement the used Qt classes QString, QList, QSet, QHash, and maybe others (only the member functions which are necessary). Or just get
401 the corresponding code from Qt (Please review the Qt licensing options, in this case. Currently, they include GNU (L)GPL and commercial).
402 The program should have independence of a particular implementation of QSet and QHash so, if you reimplement these two containers,
403 any order of elements should lead to the same generation results. Contrary behavior should be reported as a bug.
406 Languages (translations):
408 The translation files which the FET executable needs in order to be able to run in other languages are ending in .qm (like fet_**.qm)
409 and they are located in the "translations" directory in the FET distribution.
411 FET will search for translations (fet_**.qm files) in the following order:
412 1) directly in the directory where the fet executable is,
413 2) the directory "translations" in the directory where fet executable is,
414 3) the directory /usr/share/fet/translations (under GNU/Linux or Mac OS X).
416 So, on:
417 Windows: if fet.exe is in C:\fet-v.v.v, fet will search for the file fet_**.qm in
418 C:\fet-v.v.v and then in C:\fet-v.v.v\translations
419 GNU/Linux: if the fet executable is in ~/fet-v.v.v, fet will search for the file fet_**.qm in
420 ~/fet-v.v.v, then in ~/fet-v.v.v/translations and then in /usr/share/fet/translations
421 Mac OS X: the operation is approximately similar to the one for GNU/Linux.
422 The difference is that it seems that the fet application on Mac OS X contains in turn other directories (application directories),
423 so FET will search for the translations inside these application directories, not in the fet-v.v.v directory. The GNU/Linux style fet executable
424 seems to be located in fet-v.v.v/fet.app/Contents/MacOS, so FET will search for the file fet_**.qm in the directory
425 fet-v.v.v/fet.app/Contents/MacOS, then in the directory fet-v.v.v/fet.app/Contents/MacOS/translations,
426 then in the directory /usr/share/fet/translations.
427 Please see also the Mac OS X note from the section "Running FET".
428 More notes for the Mac OS X platform, from a user: copying the translations/ directory into the directory fet.app/Contents/MacOS/ is
429 possible from the command line in X11 xterm (but it is not possible with the finder program, because the file extension ".app" is
430 exclusive for applications, so the program finder interprets a directory with the extension ".app" as an application).
432 What to do if you get stuck with an unknown language: in each language, the submenu (Settings->)Language is translated also in English
433 (like: Limba/Language in Romanian). You can select the US English language (en_US abbreviation) and then close and restart FET (press the middle button
434 from the dialog that appears after trying to close FET, so that FET will exit without saving the current file).
435 Another solution: modify the FET settings on your operating system:
436 - Under GNU/Linux, and maybe Mac OS X, usually in your $HOME/.config directory you'll find a directory "fet",
437 containing file "fettimetabling.conf". Edit that file - the line beginning with language, instead of language=... (for instance, language=ro),
438 make it language=en_US (case sensitive).
439 - Under Windows: run regedit.exe (Registry Editor), search key "fet". You will find a section "fet" with sub-section "fettimetabling".
440 Modify the value name language (from, for instance, ro, or other language) to have the value data en_US (5 characters, case sensitive).
441 Another solution: simply remove the translation files (or move them so they are not available to the fet executable) and start FET. It will report
442 that the custom language is not found and it will revert to en_US.
447 Some hints in the directory "fet-v.v.v/doc/" (under GNU/Linux or Mac OS X, they may be found in usr/share/doc/fet/ directory).
448 Some other hints in the program Help menu.
449 You may find more documentation on the FET homepage.
452 Input files:
454 You can open a few sample input files in "fet-v.v.v/examples/" directory
455 (under GNU/Linux or Mac OS X, they may be found in /usr/share/fet/examples/)
458 Uninstalling FET:
460 GNU/Linux, and maybe Mac OS X: type "make uninstall" with root permissions. Then,
462 GNU/Linux and Windows:
463 Remove the directory fet-v.v.v. Also, you may want to remove the directory with the fet results (default: $HOME/fet-results).
464 This will leave the settings of FET on your system. FET stores its settings in your operating system's dedicated section.
465 If you really want to get rid of everything FET created, read below.
467 To completely remove stored FET settings from your operating system:
470 Usually, in your $HOME/.config directory you will find a directory "fet" containing the file "fettimetabling.conf".
471 Remove the directory "fet" and its contents.
473 Mac OS X: It seems that the configuration file might be: $HOME/Library/Preferences/com.fet.fettimetabling.plist
476 Run regedit.exe (Registry Editor), search for the key "fet". You will find a section "fet" with the subsection "fettimetabling".
477 Remove the "fet" section and its contents.
