Usage: makepkg package_name.tgz
(or: package_name.tbz, package_name.tlz, package_name.txz)
Makes a Slackware compatible package containing the contents of the current
and all subdirectories. If symbolic links exist, they will be removed and
an installation script will be made to recreate them later. This script will
be called "install/doinst.sh". You may add any of your own ash-compatible
shell scripts to this file and rebuild the package if you wish.
options: -l, --linkadd y|n (moves symlinks into doinst.sh: recommended)
-p, --prepend (prepend rather than append symlinks to an existing
doinst.sh. Useful to link libraries needed by
programs in the doinst.sh script)
-c, --chown y|n (resets all permissions to root:root 755
- not generally recommended)
If these options are not set, makepkg will prompt as appropriate.
