Shell packer

Give Shellpack lines of text, and shellpack compresses them to a minimal count of command line expressions needed to evaluate to the specified parameters.

An example data set:

bisqwit@mist:~/src/shellpack$ grep sfnet ~bisqwit/.snewsrc|head -n 5|sed 's/:.*//'            
sfnet.atk.ohjelmointi
sfnet.atk.ohjelmointi.moderoitu
sfnet.atk.ohjelmointi.alkeet
sfnet.tiede.matematiikka
sfnet.tiede.fysiikka

Compressing:

bisqwit@mist:~/src/shellpack$ grep sfnet ~bisqwit/.snewsrc|head -n 5|sed 's/:.*//'|./shellpack
sfnet.{atk.ohjelmointi{,.alkeet,.moderoitu},tiede.{fys,matemat}iikka}

Testing:

bisqwit@mist:~/src/shellpack$ for s in sfnet.{atk.ohjelmointi{,.alkeet,.moderoitu},tiede.{fys,matemat}iikka};do echo "$s";done
sfnet.atk.ohjelmointi
sfnet.atk.ohjelmointi.alkeet
sfnet.atk.ohjelmointi.moderoitu
sfnet.tiede.fysiikka
sfnet.tiede.matematiikka

So yep, it works. It sorts the input while doing that, too.
