alien Documentation

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the steelblue colored "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies alien_8.95.4.tar.xz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).
README
Please read alien's man page for general documentation.

Getting alien:

  The newest versions of alien are available at the alien home page; drop by
  http://kitenet.net/~joey/code/alien/

Other things you'll need:

  To use alien, you will need several other programs. Alien is a perl
  program, and requires perl version 5.004 or greater. If you use slackware,
  make sure you get perl 5.004, the perl 5.003 in slackware does not work
  with alien!

  To convert packages to or from rpms, you need the Red Hat Package Manager;
  get it from Red Hat's ftp site. If your distribution (eg, Red Hat)
  provides a rpm-build package, you will need it as well to generate rpms.

  If you want to convert packages into debian packages, you will need the
  dpkg, dpkg-dev, and debhelper (version 3 or above) packages, which are
  available on http://packages.debian.org

  To convert to/from stampede packages, you will need bzip2.

  Attention, Slackware, Red Hat, and Stampede users: Bruce S. Babcock
  <babcock@math.psu.edu> has put together an "alien-extra"
  package of all the extra files you need to use alien on
  a Red Hat or Slackware system. (Debian systems automatically have all
  required files.)
  
  The Slackware version is at 
  	ftp://ykbsb2.yk.psu.edu/pub/alien/alien-extra.tgz
  The RedHat version is at
  	ftp://ykbsb2.yk.psu.edu/pub/alien/alien-extra.rpm
  The Stampede version is at
  	ftp://ykbsb2.yk.psu.edu/pub/alien/alien-extra.slp

Note:

  Alien is really designed to be used to convert from alien file formats to
  the packaging format used by the distribution you run it on. Of course,
  it can also convert from your distribution's native format to alien
  formats, or from one alien format to another. Do be warned though, that
  if these latter types of conversions are done, the generated packages may
  have incorrect dependancy information. This is known to be true if you
  convert a rpm into a deb on a Red Hat system, for example. Even with
  alien-extra installed, dpkg will be unable to properly calculate library
  dependancies for the deb it is creating, and you will get a package
  without any library dependancies.

Programs that use alien:

  I know of one program that acts as a frontend to alien - kpackviewer is a
  package viewer that can convert between package formats by using alien. Its
  homepage is at http://www.momentus.com.br/users/hook/kpackviewer.html

  Corel also appears to have (or had) something in Corel linux that
  uses alien.

Please report any bugs in alien to the author: 

  Joey Hess <joeyh@debian.org>

  It is helpful to provide a log of alien --veryverbose reproducing the
  bug. I may also ask for the package that exposes the problem you saw.
