EPM is an open source UNIX software and file packaging program that generates distribution archives from a list of files. EPM provides a complete, cross-platform software distribution solution for your applications.
EPM generates both native and "portable" script-based distribution packages complete with installation and removal scripts and standard install/uninstall GUIs. The installers can be customized with product logos, "readme" files, and click-wrap licenses as desired.
- Creates software packages that can be distributed on disc or over the Internet!
- Supports AIX, Debian GNU/Linux, FreeBSD, HP-UX, IRIX, OS X, NetBSD, OpenBSD, Red Hat Linux, Slackware Linux, Solaris, and Tru64 UNIX.
- Provided as free software under the GNU General Public license.
The EPM book teaches you how to create your own software packages that can be distributed over the Internet and on disc.
