I want to propose to rename the file SHA1SUM in the iso directory in
more meaningful like for example:
for Fedora Core 7. It is file with a gpg signature in it, for this reason
the .gpg suffix and after opening it with gpg it is a file containing sha1
signatures and therefore the .sha1 suffix. The FC-7 shows directly where the
files belongs to.
.gpg sounds like it's a gpg *key*, not a randomly gpg signed file.
