I'm sure it will not be perfect, certainly not with the first attempt!
But it will be a significant improvement w.r.t to the current release.

The point is: there are no defined keywords, not in the MPLAB .dev files
and not in the datasheets, there are only 'descriptions' (which can be 2
letters, but are frequently several words).
Seb: for this reason datasheet parsing is no option, I think.
But pragma fuse_def requires a keyword, which should preferrably be easy
to remember by a Jal user. HS and XT are good examples, but there are
far more bad examples in the current device files.
In the current situation the parsing of the descriptions generates many
duplicate keywords. Because of this there is no 'pragma OSC' declared in
the device files, and consequently these settings cannot be selected by
the user. A table with unique keywords will also solve this issue.
I don't expect maintenance of this table to be a time-consuming task:
- the time between MPLAB releases is counted in months
- a compare script will quickly reveal differences
- most descriptions won't change from one to the other release
Of course 'devicefiles.html' will contain a list of possible keywords.
But not every keyword is applicable to every PIC, the device file will
have to be consulted for the allowed keywords for a specific PIC (I
don't think it is practical to include a keyword-per-fusebit-per-PIC
table in the user docs!).
