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.

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. --remove-rpaths (remove all rpaths from ELF objects) --remove-tmp-rpaths (remove rpaths from ELF objects if we find one that contains '/tmp') If these options are not set, makepkg will prompt if appropriate.
