The package description is:
FuseCompress provides a mountable Linux filesystem which transparently
compress its content. Files stored in this filesystem are compressed
on the background and Fuse allows to create a transparent interface
between compressed files and user applications.
I don't use fusecompress anymore hence am orphaning it. There are some
bugs in fusecompress. Unfortunately, upstream has not been very
responsive. All packaging details for fusecompress is available at:
