NAME

       sgmlpre - handle SGML conditionalization for SGML-tools

SYNOPSIS

       sgmlpre [options] ...

DESCRIPTION

       This manual page documents briefly the sgmlpre commands.  This manual page was written for
       the Debian GNU/Linux distribution because the original program does not have a manual page
       for sgmlpre.

       sgmlpre is a program that handle SGML conditionalization for SGML-tools

       It  is used by other programs in sgml-tools (v1), and usually normal user does not need to
       use this program directly by himself.

       Following is quoted from the header in the source code.

              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).

OPTIONS

       The program does not support normal command line options.
