* unfuck quoted-printable crap
* more robust plaintext extraction from mime
* more efficient month sort in the year view
* I think sort(1) might have a bug with -M and pos1
* or stupid awk can just produce an ordered list
* a lot of speedup
* this might mean an external index
* or it might just mean aggressive in-app cache
* do we want threading in the month views
* decode non-ascii header values (From: especially)

INSTALL:
put this folder in e.g. /werc/apps/mdir
put your mdir in e.g. /werc/sites/example.com/mail/
(such that all the messages land in /werc/sites/example.com/mail/mbox/)
mkdir /werc/sites/example.com/mail/_werc
echo "conf_enable_mdir" > /werc/sites/example.com/mail/_werc/config
good luck.
