+Usage: makepkg package_name.tgz

+
+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)
+ --threads <number> For xz/plzip compressed packages, set the max
+ number of threads to be used for compression. Only has an
+ effect on large packages. For plzip, the default is equal to
+ the number of CPU threads available on the machine. For xz,
+ the default is equal to 2 (due to commonly occuring memory
+ related failures when using many threads with multi-threaded
+ xz compression).
+ --compress <option> Supply a custom option to the compressor.
+ This will be used in place of the default, which is: -9
+ --acls Support storing POSIX ACLs in the package. The resulting
+ package will not be compatible with pkgtools version < 15.0.
+ --xattrs Support storing extended attributes in the package. The
+ resulting package will not be compatible with pkgtools
+ version < 15.0.
+
+If these options are not set, makepkg will prompt if appropriate.
