-.IX Header "DESCRIPTION"
-\&\fBtypog-grep\fR is a tailored post-processor for LaTeX log files
-and the \f(CW\*(C`typoginspect\*(C'\fR environment as provided by package\ typog.
-It shares more with the venerable
-\&\fBsgrep\fR <https://www.cs.helsinki.fi/u/jjaakkol/sgrep.html>
-than with \s-1POSIX\s0\ \fBgrep\fR <https://pubs.opengroup.org/onlinepubs/9699919799/utilities/grep.html>.
-.PP
-The LaTeX user brackets her text in
-.PP
-.Vb 3
-\& \ebegin{typoginspect}{ID}
-\& Text and code to investigate
-\& \eend{typoginspect}
-.Ve
-.PP
-where \fI\s-1ID\s0\fR is used to identify one or more bracketed snippets.
-\&\fI\s-1ID\s0\fR does not have to be unique.
-The \fI\s-1REGEXP\s0\fR mechanism makes it easy to select groups of related \fI\s-1ID\s0\fRs
-if they are named accordingly.
-.PP
-In \fILOG-FILE\fR the environment shows up, packed with tracing information, as
-.PP
-.Vb 3
-\& <typog\-inspect id="ID" job="JOB\-NAME" line="LINE\-NUMBER" page="PAGE\-NUMBER">
-\& Trace Data
-\& </typog\-inspect>
-.Ve
-.PP
-where all the capital-letter sequences are meta-variables
-and in particular
-\&\fIJOB-NAME\fR is the expansion of \f(CW\*(C`\ejobname\*(C'\fR,
-\&\fILINE-NUMBER\fR is the LaTeX source file line number
-of the beginning of the \f(CW\*(C`typoginspect\*(C'\fR environment,
-and \fIPAGE-NUMBER\fR is the page where
-the output of \f(CW\*(C`Text\ and\ code\ to\ investigate\*(C'\fR occurs.
-.PP
-\&\fBtypog-grep\fR reveals the contents of \fILOG-FILE\fR
-between \f(CW\*(C`<typog\-inspect id="\f(CIID\f(CW" ...>\*(C'\fR
-and \f(CW\*(C`</typog\-inspect>\*(C'\fR excluding the XML-tags.
-Access the \fIJOB-NAME\fR, \fILINE-NUMBER\fR, and \fIPAGE-NUMBER\fR
-with the commandline options
-\&\fB\-\-job\-name\fR, \fB\-\-line\-number\fR, and \fB\-\-page\-number\fR, respectively.

-.PP
-\&\f(CW\*(C`typoginspect\*(C'\fR environments can be nested.
-\&\fBtypog-grep\fR respects the nesting,
