epm 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 epm-5.0.0.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).

ESP Package Manager (EPM)

What is EPM?

EPM is a simple cross-platform tool that generates software and patch distributions in various formats from a list of files. Supported formats include:

  • AIX software packages ("installp")
  • AT&T software packages ("pkgadd"), used by Solaris and others
  • BSD packages ("pkg_create")
  • Compaq Tru64 UNIX ("setld")
  • Debian Package Manager ("dpkg")
  • HP-UX software packages ("swinstall")
  • IRIX software manager ("inst", "swmgr", or "tardist")
  • macOS software packages ("name.pkg")
  • Portable (installation and removal scripts with tar files)
  • Red Hat Package Manager ("rpm")
  • Slackware software packages ("name.tgz")

EPM also includes graphical "setup" and "uninstall" programs that can be provided with your distributions to make installation and removal of more than one package a snap. The installers can be customized with product logos, "readme" files, and click-wrap licenses as desired.

EPM is provided as free software under version 2 of the Apache License (ALv2).

How is this releated to the official EPM?

Starting with version 4.5.2, this is, in fact, the official EPM distribution.

How Do I Compile EPM?

See the file INSTALL.md for more info on that.

How Do I Use EPM?

Please look at the EPM manual. A preformatted copy is included with the source archive in the file doc/epm-book.html.

An example EPM software list file is provided with this distribution in the file epm.list.

Do I Have to Pay to Distribute Software Using EPM?

No! EPM is free software and any installations you create are unencumbered by licensing of any kind, not even the GPL or the ALv2.
