-.SH DESCRIPTION
-.
-.B mom
-is a macro set for groff, designed primarily to format documents for
-PDF and PostScript output.
-.P
-.B mom
-provides two categories of macros: macros for typesetting, and
-macros for document processing.
-The typesetting macros provide access to groff's typesetting
-capabilities in ways that are simpler to master than groff's
-primitives.
-The document processing macros provide highly customizable markup
-tags that allow the user to design and output professional-looking
-documents with a minimum of typesetting intervention.
-.P
-Files processed with
-.B pdfmom
-(man(@MAN1EXT@)
-.BR pdfmom\c
-), with or without the
-.RI -T ps
-option, produce PDF documents.
-The documents include a PDF outline that appears in the
-\[oq]Contents\[cq] panel of document viewers, and may contain
-clickable internal and external links.
-.P
-When
-.RI -T ps
-is absent,
-.B groff's
-native PDF driver,
-.B gropdf\c
-, is used to generate the output.
-When given, the output is still PDF, but processing is passed over to
-.B pdfroff\c
-, which uses
-.B groff's
-PostScript driver,
-.B grops\c
-\&.
-Not all PDF features are available when
-.RI -T ps
-is given; its primary use is to allow processing of files with
-embedded PostScript images.
-.P
-Files processed with
-.B groff -mom
-(or
-.BI "-m " mom
-) produce PostScript output by default.
-.P
-mom comes with her own very complete documentation in HTML format.
-A separate PDF manual,
-.I Producing PDFs with groff and mom\c
-, covers full mom/PDF usage.

-.\" The .SH was moved to the beginning in order to appease `apropos'.

-.
-.
-This man-page contains information just as in groff(7),
-.I mom macros
-and
-.I mom escape sequences
-in alphabetical order.
-.
-.
-.P
-The logical order of
-.I mom macros
-and
-.I mom escape sequences
-is very well documented in
-.
-.TP
-.B \%@HTMLDOCDIR@/\:mom/\:toc.html
-\[en] entry point to the HTML documentation
-.
-.
-.P
-That is quite good for beginners, but power users need more
-documentation in reference style.
-.
-.
-.P
-So we restrict this man-page to the alphabetical order of macros and
-escape sequences.
-.
-But, so far, we take all documentation parts from the
-.I toc.html
-file, just in a more useful order.
-.
-Moreover, this is a man-page, so you can read it with
-.BR groffer ,
-instead of some strange webbrowser for
-.BR toc.html .
-.
-So this man-page is nothing new, but only a logical arrangement.

-.B .T_MARGIN
-calculates the vertical position of the first line of type on a page
-by treating the top edge of the printer sheet as a baseline.
-Therefore, 
-.RS
-.EX
-.B .T_MARGIN 1.5i
-.EE
-.RE
-puts the baseline of the first line of type 1-1/2 inches beneath the
-top of the page.
-.
-.P
-Note:
-.B .T_MARGIN
-means something slightly different when you’re using the document
-processing macros.
-.
-See Top and bottom margins in document processing for an explanation.
-.
-.P
-IMPORTANT:
-.B .T_MARGIN
-does two things: it establishes the top margin for pages that come
-after it and it moves to that position on the current page.
-.
-Therefore,
-.B .T_MARGIN
-should only be used at the top of a file (prior to entering text) or
-after NEWPAGE, like this:
-.RS
-.EX
-.B .NEWPAGE
-.B .T_MARGIN 6P
-.I <text>
-.EE
