This is the GNU `groff' document formatting system.  The version
number is given in the file VERSION.

Included in this release are implementations of `troff', `pic', `eqn',
`tbl', `grn', `refer', `-man', `-mdoc', `-mom', and `-ms' macros, and
drivers for `PostScript', `PDF', `TeX DVI' format, `HP LaserJet 4'
printers, `Canon CAPSL' printers, `HTML' and `XHTML' formats (beta
status), and typewriter-like devices.  Also included is a modified
version of the Berkeley `-me' macros, the enhanced version `gxditview'
of the X11 `xditview' previewer, and an implementation of the `-mm'
macros contributed by Joergen Haegg (jh@axis.se).

See the file `INSTALL' for installation instructions.  You require
a C++ compiler.

The file `NEWS' describes recent user-visible changes to `groff'.

`groff' is free software.  See the file `COPYING' for copying
permission.

The file `PROBLEMS' describes various problems that have been
encountered in compiling, installing, and running `groff'.

The file `MORE.STUFF' contains information about add-on packages
useful for groff.

The most recent released version of `groff' is always available by
anonymous ftp from `ftp.gnu.org' in the directory `gnu/groff'.

The current development version of `groff' is available from a `CVS'
repository.  You can access it by first selecting a parent directory
in which to create a working copy (call it, say, `~/cvswork'), and
then executing the commands

  cd ~/cvswork
  cvs -d:pserver:anonymous@cvs.savannah.gnu.org/sources/groff -z5 co groff

This creates a subdirectory, `~/cvswork/groff', with a `checked out'
copy of the `CVS' repository.  An update of this working copy may be
achieved, at any later time by invoking the commands

  cd ~/cvswork/groff
  cvs -z5 update -dP

Please read the `CVS' info pages for further details.

Finally, it is possible to access the `CVS' with a web browser by
pointing it to

  http://savannah.gnu.org/cvs/?group=groff

Alternatively, you can download snapshots (which are updated twice a
day).  The complete `groff' source as a single file is available at

  http://groff.ffii.org/groff/devel/groff-current.tar.gz

A diff file relative to `groff-<version>', the latest official `groff'
release, is available at

  http://groff.ffii.org/groff/devel/groff-<version>-current.diff.gz

Assuming that `groff-<version>.tar.gz' and
`groff-<version>-current.diff.gz' are in the same directory, do the
following to apply the diff file:

  tar xzvf groff-<version>.tar.gz
  cd groff-<version>
  gunzip -c ../groff-<version>-current.diff.gz | patch -p1

Depending on your requirements, you may need at least some of the
following tools to build `groff' directly from its source:

  ghostscript
  the psutils package
  the netpbm package
  texinfo 4.8
  bison >= 1.875b or byacc

Note that `texinfo' and `bison' or `byacc' are required only for
building from `CVS' sources (either a checked out working copy, or a
daily snapshot).  They are not required for building from a stable
release tarball.  Also note that the version numbers stated are the
minimum supported.  No version of `texinfo' < 4.8 works, and the
original release of `bison' 1.875 is known not to work; you *may* find
that `bison' releases < 1.875 work, but in case of difficulty, please
update to a later version *before* posting a bug report.

For *all* sources, you need ghostscript for creation of either `PDF' or
`HTML' output; the `netpbm' and `psutils' packages are required only
for `HTML' output (and for compilation from the CVS).  If you don't
intend to produce output in either of these formats, then these
packages are unnecessary.

Additionally, producing `PDF' output directly with the `gropdf' device
needs a working installation of Perl.  The same is true for the `chem'
preprocessor.

In Linux Debian, the installation of `texinfo' is dangerous.  For it
creates a file `install-info' that blocks the system installation.  So
the created `/usr/local/bin/install-info' must be renamed.

The `groff' configure script searches for the X11 headers and
libraries `Xaw' and `Xmu'.  So the corresponding developer packages of
your system must be installed, otherwise `groff' does not install
`gxditview' and the `-TX*' devices.  In Debian, the developer packages
are `libxaw7-dev' and `libxmu-dev'.

Please report bugs using the form in the file `BUG-REPORT'; the idea
of this is to make sure that FSF has all the information it needs to
fix the bug.  At the very least, read the `BUG-REPORT' form and make
sure that you supply all the information that it asks for.  Even if
you are not sure that something is a bug, report it using
`BUG-REPORT': this enables us to determine whether it really is a bug
or not.

Three mailing lists are available:

  bug-groff@gnu.org          for reporting bugs
  groff@gnu.org              for general discussion of groff
  groff-commit@gnu.org       a read-only list showing commitments
                             to the CVS repository

To subscribe, send a mail to <list>-request@<domain> (example:
groff-request@gnu.org for the `groff' list) with the word `subscribe'
in either the subject or body of the email (don't include the quotes).
Alternatively, you may subscribe by visiting the web pages at

  http://lists.gnu.org/mailman/listinfo/bug-groff
  http://lists.gnu.org/mailman/listinfo/groff
  http://lists.gnu.org/mailman/listinfo/groff-commit

Each of these web pages also provides a link to a browseable archive of
postings to the corresponding mailing list.
