tcplay also uses dm-crypt. The author found that the Truecrypt format 
documentation had a lot of errors; see the tcplay README for details.

It appears that there are provisions for using an API from tcplay from 
other programs, but I haven't really examined that.

Which is exactly why I'm trying to get the BSD-licensed tcplay into Fedora.

It would be great to also have a way for users to deal with it through 
GUI tools, but tcplay does not provide that.
