Slackware package maker, version 3.14159.

Searching for symbolic links:
bin/compress -> /usr/bin/compress
bin/uncompress -> compress
usr/bin/uncompress -> compress

Making symbolic link creation script:
( cd bin ; rm -rf compress )
( cd bin ; ln -sf /usr/bin/compress compress )
( cd bin ; rm -rf uncompress )
( cd bin ; ln -sf compress uncompress )
( cd usr/bin ; rm -rf uncompress )
( cd usr/bin ; ln -sf compress uncompress )

It is recommended that you make these lines your new installation script.

Would you like to make this stuff the install script for this package
and remove the symbolic links ([y]es, [n]o)? y


Removing symbolic links:
removed `./bin/compress'
removed `./bin/uncompress'
removed `./usr/bin/uncompress'

Creating your new ./install/doinst.sh...

This next step is optional - you can set the directories in your package
to some sane permissions. If any of the directories in your package have
special permissions, then DO NOT reset them here!

Would you like to reset all directory permissions to 755 (drwxr-xr-x) and
directory ownerships to root.root ([y]es, [n]o)? n
