晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

More stuff for groff
====================
Windows 32
----------
Here are two ports using the gcc compiler and other GNU tools:
. Cygwin:
http://sources.redhat.com/cygwin/
Look for a convenient mirror site in
http://sources.redhat.com/cygwin/mirrors.html
At any of those mirrors, groff can be found in the directory
latest/groff.
. Kees Zeelenberg <c.zeelenberg@hccnet.nl>:
http://gnuwin32.sourceforge.net/packages/groffl.htm
This port includes recent versions of grap and deroff.
dos
---
Binaries for Eli Zaretskii's port using the djgpp compiler are available
from
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2gnu/gro*b.zip
and its mirrors; for installation details please read `arch/djgpp/README'.
This port also runs on Windows 32 systems, except Windows 2000.
grap
----
An implementation of Kernighan & Bentley's grap language for typesetting
graphs. Written by Ted Faber <faber@lunabase.org>. The actual version
can be found at
http://www.lunabase.org/~faber/Vault/software/grap/
A djgpp port which runs on dos and most Windows 32 systems (Windows 95,
Windows 98, Windows NT) done by Kees Zeelenberg <c.zeelenberg@hccnet.nl>
is available from
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2apps/
It is intended to be used with the djgpp port of groff.
A Windows 32 port is included in the groff package available from
http://gnuwin32.sourceforge.net/
plot2dev
--------
This utility program can convert plot graphics to either pic or gremlin
files. It has been written by Richard Murphey <richard-murphey@rice.edu>
and Daniel Senderowicz <daniel@synchrods.com> (who has added the gremlin
driver). The actual version can be found as
ftp://ftp.ffii.org/pub/groff/plot2dev-x.x.tar.gz
troffcvt
--------
From the web page:
troffcvt is a translator that turns troff input into a form that can be
more easily processed. The troffcvt distribution comes with
postprocessors that turn troffcvt into various destination formats such
as HTML (Hypertext Markup Language), RTF (Rich Text Format) or plain
text.
Note that you need a lot of additional packages to compile troffcvt;
everything is available from
http://www.primate.wisc.edu/software/troffcvt/
unroff
------
From the README file:
Unroff is a Scheme-based, programmable, extensible troff translator with
a back-end for the Hypertext Markup Language. Unroff is free software
and is distributed both as source and as precompiled binaries.
http://www.informatik.uni-bremen.de/~net/unroff/unroff.html
You need als Elk, the Scheme based Extension Language Kit, which is
available from
http://www.informatik.uni-bremen.de/~net/elk
deroff
------
Deroff removes roff constructs from documents for the purpose of indexing,
spell checking etc.
Michael Haardt's <michael@moria.de> implementation is a little smarter
than traditional implementations, because it knows about certain -man and
-mm macros. It is able to generate a word list for spell checking tools
or omit headers for sentence analysis tools. It can further generate
cpp-style #line lines.
http://www.moria.de/~michael/deroff/
Version 1.6 compiled with DJGPP (for MS-DOS and all Windows 32 systems,
i.e. Windows 95, Windows 98, Windows NT) is available from
ftp://ftp.simtel.net/pub/simtelnet/gnu/djgpp/v2apps/
and its mirrors.
A Windows 32 port of version 1.8 is available from
http://gnuwin32.sourceforge.net/
David Frey <dfrey@debian.org> has also written a deroff implementation
for Debian; it is available from
ftp://ftp.debian.org/debian/pool/main/d/deroff/
texi2html
---------
This package contains beta support for a backend to convert files from
texinfo format to a troff input file (using the -me macros):
texi2html --init roff.init ...
URL:
http://savannah.nongnu.org/download/texi2html/
doclifter
---------
doclifter lifts troff macro markup to XML-Docbook. It doesn't do raw troff
at all well (raw troff has insufficient structural information) but it
handles manual pages, ms, mm, and me markup, producing clean lifts
to valid XML more than 96% of the time. pic markup is translated to SVG,
eqn markup to Presentation MathML.
doclifter with the -w option behaves as a portability checker and validator,
warning about constructs that aren't portable across *roff implementations
and viewers.
It is available from
http://catb.org/~esr/doclifter
pic2plot
--------
pic2plot, part of the GNU plotutils package, can lift pic markup to SVG.
The plotutils package is available at
http://www.gnu.org/software/plotutils/
miscellaneous
-------------
. Ralph Corderoy's excellent page on troff:
www.troff.org
There are links for virtually everything related to troff.
. Dr. Robert Hermann's groff gems are available from
http://www.eas.slu.edu/People/RBHerrmann/GROFF/index.html
At present there are examples for
o creating business cards
o using groff to make large format posters for presentations
. Robert Marks's collection of useful macros and scripts is available from
http://www.agsm.edu.au/~bobm/odds+ends/scripts.html
Description:
o `polish': Is a sed (= the Unix stream editor) script that does many
things to ASCII text. Amongst other things, it breaks lines at new
sentences, reduces upper-case acronyms by one point size, adds
diacriticals, changes simple quotes into smart quotes, and makes a few
simple grammar checks. The best way to see what it does is to run it
as a sed script file (or files) on a text file and then compare the
output file with the original.
o `DropCaps' is a troff script which replaces the initial letters of
paragraphs immediately after H1 and H2 headings with drop-capitals of
specified point size, and automatically flows the text around the new
drop cap.
o `AJM Header' is a set of troff macros used in production of the
Australian Journal of Management. They use the Memorandum Macros (mm)
of AT&T, and so should be invoked with the UNIX troff -mm flag; they
should also work with the GNU troff -mm flag.
. Various contributed stuff like additional font files, macro packages, and
documentation can be found at
http://groff.ffii.org/groff/contrib/
. Thomas Baruchel <baruchel@libertysurf.fr> has developed Meta-tbl, a tbl
postprocessor to manipulate table cells (like adding gray shades). The
latest version can be found at
http://perso.libertysurf.fr/baruchel/
. gpresent, written by Bob Diertens <bobd@science.uva.nl>. From the README
file:
gpresent is a package for making presentation with groff and acroread.
It consist of a set of macros to be used with groff and a post-processor
for manipulating the PostScript output of groff. Without the use of the
PAUSE macro, it can also be used for making slides.
It is available from
www.science.uva.nl/~bobd/useful/gpresent/
