The software is a perl-script that i developed myself. Md5sum wasn't 
"intelligent" enough for me(*) and i didn't really look if there was any 
existing software. So i began with a small script around "Digest::MD5" 
and it grew from there. The script (i call it "md5tool.pl") is mostly 
generic, altough there are a few things specific for my environment 
hardcoded into it.

For e.g. the script also records mtime, size and filetype with x/y-sizes 
for a few image-types.

With the mtime/size information the script can check if a file has been 
changed and update the stored MD5-sum.
