Revision 1.23, Sun Feb 6 20:36:36 2011 UTC (13 years, 7 months ago) by kristaps
Branch: MAIN
Changes since 1.22: +2 -1 lines
Add initial EQN support to mandoc. This parses, then throws away, data
between EQ and EN roff blocks. EQN is different from TBL in that data
after .EQ is unilaterally considered an equation until an .EN. Thus,
there's no need to jump through hoops in having table spans and so on.
This is ONLY the parse code framework in libroff. EQN is not yet passed
into the backends.
