# 20220411 bkw: Modified by SlackBuilds.org, BUILD=2:
# - get rid of (empty) /usr/share/doc dir. yes, it has a file in it
#   called .buildinfo, but this is utterly useless in a binary
#   package (it's more-or-less a cache to keep from rebuilding the
#   docs when they haven't changed, only useful if you're rebuilding
#   the same source dir multiple times).
# - get rid of empty /usr/share/fish/man/man1/ dir.
# - add update-desktop-database to doinst.sh, since v3.4.0 adds a
#   .desktop file.
# - use absolute path to icon in doinst.sh.
# - tighten up the script a bit.
# Note to maintainer: The build will create the man pages and
# HTML docs if Sphinx is installed, or use pre-generated ones if
# not. Nothing wrong with this, per se, but it might lead to trouble
# later (if Sphinx gets upgraded to a version that won't work with
# fish's build process, e.g). Your mission, should you choose to
# accept it, is to modify the cmake parameters (or even patch the
# CMakeLists.txt) to make it always use the pre-generated HTML and
# manpages (and ignore Sphinx, if found).
