# 20230630 bkw: Modified by SlackBuilds.org, BUILD=2:
# - use BUILDROOT instead of --prefix=$PKG/usr, avoids compiling the
#   $PKG path into the binary.
# - fix 32x32 icon (it was 31x31).
# - don't include empty icon dirs in the package.
# - make .desktop file validate.

# Thanks to Gentoo htmldoc's .ebuild maintainer for hints about configure's
# workaround, and for a patch to fix CVE-2009-3050.

#
# Feb 01 2017: Alfredo
# Update script for html-1.8.29, fix the problem with /usr/share/htmldoc/data
# not being copied into the package
#
#
# May 01 2020: organixpear
# Update script for htmldoc-1.9.8
# This was a needed update as htmldoc-1.8.29 was 3 years out of date
# and the build would fail on recent versions (current) of Slackware.
# gnutls support was also found to be working in htmldoc-1.9.8 so
# support was added. Misc updates and cleanups to install commands.
