.B sgmlpre
-- handle SGML conditionalization for SGML-tools
by Eric S. Raymond <esr@thyrsus.com>, 3 Nov 1997

Filter SGML according to conditionalizing markup.  Argument/value pairs
from the command line are matched against the attributes of <#if> and
<#unless> tags.  Spans between <#if>/</#if> are passed through unaltered
if there is no attribute mismatch; spans between <#unless></#unless> are
passed if there is at least one attribute mismatch.  An attribute mismatch
happens  if an attribute occurs in both the command-line arguments and the
tag, but the values do not match.  Value matching is by string equality,
except that "|" is interpreted as an alternation character.  Even if a span
is not passed through, its newlines are (this to avoid messing up the
line  numbers in error messages).

This lexer requires flex.  Limitations; attribute names may only be
256 chars long, values may be only 16384 (YY_BUF_SIZE) characters long.
Doesn't do checking that only </if> matches <if> and </unless> matches
<unless> (that would need a stack and introduce another limit).
