The new format allows for downloading and importing only a part of the
database - useful when only the metadata is required - and doesn't
include the wasteful preformatted HTML cache.
This also ensures that the new import.sql script is actually usable and
in sync with the actual database. The old schema.sql was neither.
(And this simplifies my backup scripts)
Primarily aimed at reducing the size of the old 'man' (now: files)
table, using smaller integers to refer to man contents and text fields,
and storing a shorthash as an integer for quick lookups. This better
normalization also removes the need to keep a separate 'man_index' cache
for the search function.
The old schema wasn't necessarily bad, but I was in the mood for some
optimizations. And a little cleanup.
Prolly introduces a bunch of new bugs, I haven't tested this too well.
The XML thing is supposed to be used for auto-completion, of course. The
current search implementation is very, very stupid and simple: Just a
prefix match on the man name, and simple detection of section stuff. I
suppose it'll suffice for now.
