Having issues with some conference or journal requiring you to provide a single LaTeX file and all graphics in the root directory? Well, this is a good tool.
PS: I used **version `0.4.1`** because `0.5.0` caused problems.
When you delete or move a message, most e-mail programs ("clients") simply hide the message and mark it as ready for physical deletion later on. The "deleted" messages are still stored in the folder - even emptying the Trash does not remove them. The hidden messages are not physically removed until the folder is compacted (not to be confused with compressing a file). If you don't compact your mail folders periodically, they can grow very large.
