Category in mimetypes.

[Stef Bon]

Hi Thomas,

thanks for your answer.

Now a few days later, I go for the hardcoded lists. Not really
hardcoded lists, the user can modify them.

When making a backup of a directory (not recursive), in my idea I go
for a "backup profile".
Directories you want to backup to my experience are for example:

- a directory with code files: c- and h-files, and the README,
Changes, NEWS, documentation and some others.
- a directory with documents for resume's and lettres to aplly to a job.
- a directory with documents for work: presentations, pdf's,
spreadsheets and text documents

It looks like the best sollution is a profile:
a set of mimetypes to include (a group of mimetypes)
filenames to include
and as extra: a maximum of filesizes

My idea is to create a gui to construct:
-groups of mimetypes (like the group "programming")
-rules that apply to a directory like "backup all these files with the
mimetype which is part of group programming".
