What is groff?
==============

groff (GNU roff) is a typesetting system that reads plain text input
that includes formatting commands to produce output in PostScript,
PDF, HTML, or DVI formats or for display to a terminal.  Formatting
commands can be low-level typesetting primitives, macros from a
supplied package, or user-defined macros.  All three approaches can be
combined.

A reimplementation and extension of troff and other programs from AT&T
Unix, groff is widely available on POSIX and other systems owing to its
long association with Unix manuals, including man pages.  It and its
predecessor have produced several best-selling software engineering
texts.  groff can create typographically sophisticated documents while
consuming minimal system resources.

Obtaining groff
===============

Here are the compressed sources and a GPG detached signature[*].
  https://ftp.gnu.org/gnu/groff/groff-1.24.1.tar.gz
  https://ftp.gnu.org/gnu/groff/groff-1.24.1.tar.gz.sig

Use a mirror for higher download bandwidth.
  https://ftpmirror.gnu.org/groff/groff-1.24.1.tar.gz
  https://ftpmirror.gnu.org/groff/groff-1.24.1.tar.gz.sig

Here are the SHA-1 and SHA-256 checksums.

6bba283f8b55b74bbcafd56653876ec5d567de63  groff-1.24.1.tar.gz
dOKBl5W2r/QxrqyYPWOpyJaO6roqLrp9+LpMe0Hnz9g=  groff-1.24.1.tar.gz

The SHA-256 checksum is encoded in Base64 instead of the hexadecimal
form that most checksum tools default to.  The mechanism follows.

sha256sum < groff-1.24.1.tar.gz | cut -f1 -d\  | xxd -r -p | base64

(Because "base64" reads from a pipe, it doesn't know the file name, and
so the file name will not appear in the output.)

[*] Use a .sig file to verify that the corresponding file (without the
    .sig suffix) is intact.  First, be sure to download both the .sig
    file and the corresponding archive.  Then, verify the archive.

      gpg --verify groff-1.24.1.tar.gz{.sig,}

    If that command fails because you don't have the required public
    key, you can import it.

      wget -O 108747.asc \
        'https://savannah.gnu.org/people/viewgpg.php?user_id=108747'
      gpg --import 108747.asc

    Re-run the 'gpg --verify' command above again subsequently.


Caveats
=======

o GNU tools, or otherwise POSIX-conforming ones, are generally required
  to build on Solaris 10 or 11.  See the "PROBLEMS" file in the
  distribution archive.

o Solaris 10 has known problems with automated tests; see the "PROBLEMS"
  file in the distribution archive.
