Guncat was designed to tackle a problem encountered with (partically)
PGP encrypted files (which may be encountered in, e.g., mailboxes).
Tools to process text-files (like grep(1), or less(1)) may be used to
process those files, but standard tools like cat(1) leave PGP encrypted
sections within such files as-is. As a consequence, browsing the `real'
contents (i.e., clear-text sections and the unencrypted contents of PGP
encrypted sections) of those files is difficult.
Guncat acts like cat, but unencrypts encrypted sections encountered in
the files processed by guncat, copying the unencrypted information to
guncat's standard output stream, which may thereupon be processed by
other tools.
