+ o You can mess MD5 with SHA1 checksums in same file. This has some funny
+   consequences... Try adding both SHA1 & MD5 sums for same filename :P
  o Total Commander integration is a mess.
  o NOT overwriting sensitive data is user's responsability :)
  o I tried to make the best ".md5" parser I could with no Perl regexp.
