This file describes how to prepare `groff' for a new release.


########################################################################

The file `INSTALL.gen' shall *never* be changed manually!  It is a
generic file provided from GNU (normally called `INSTALL').

* Retrieve current versions of UnicodeData.txt[1] and the Adobe Glyph
  List (AGL)[2], and use them with
  src/utils/afmtodit/make-afmtodit-tables to update
  src/utils/afmtodit/afmtodit.tables.

[1] E.g., <https://www.unicode.org/Public/13.0.0/ucd/UnicodeData.txt>.
    Check for the latest _released_ version of Unicode at the time.
    Data for the forthcoming release may be available.
[2] <https://github.com/adobe-type-tools/agl-aglfn/blob/master/\
      glyphlist.txt>

* Update the 'gnulib' sub-module to the latest version.

* Update the copyright:

  Use ./gnulib/build-aux/update-copyright:

     export UPDATE_COPYRIGHT_USE_INTERVALS=2
     find . \
        -path ./.git -prune -o \
        -path ./gnulib -prune -o \
        ! -name "ChangeLog.*" -type f |  xargs ./gnulib/build-aux/update-copyright -

  Modify in 'src/roff/groff/groff.cpp' the 'printf' that displays the
  copyright.

* Update the release version number where it is hard-coded.
