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).
