1 /*@ S-nail - a mail user agent derived from Berkeley Mail.
2 *@ Account, macro and variable handling.
3 *@ HOWTO add a new non-dynamic boolean or value option:
4 *@ - add an entry to nail.h:enum okeys
5 *@ - run mk-okey-map.pl
6 *@ - update the manual!
7 *@ TODO . should be recursive environment based
8 *@ TODO . undefining and overwriting a macro should always be possible:
9 *@ TODO simply place the thing in a delete-later list and replace the
10 *@ TODO accessible entry! (instant delete if on top recursion level.)
11 *@ TODO . Likewise, overwriting an existing should be like delete+create
12 *@ TODO . once we can have non-fatal !0 returns for commands, we should
13 *@ TODO return error if "(environ)? unset" goes for non-existent.
