On my travels around t'interweb, I occasionally download the odd album in a lossless format. These are usually direct from a bands site or from sites like allflac.com or bandcamp.com . I like to archive these off and keep them somewhere safe. The usual procedure for this has been, create a rar archive then parity redundancy followed by unpacking the flac files, converting to mp3 and then tagging and renaming each file.
Quite frankly I was getting bored of this so created a script. It's not perfect by a long shot, but if you have the prerequisites in place, it usual does the job :)

Pop this in /usr/local/bin

Bash script here.

PREREQUISITES:
Script *MUST* be called from within the source directory.
auCDtect for checking the authenticity of the lossless. (now available in portage)

USAGE:
flacpack -V <toggle various> -N <don't encode to mp3> -h <help>
