#
# Building individual packages
# -----------------------------
# This script aids with building, unattended, the individual components.
# Before running this script, be sure to wipe the existing packages from the
# 'slackware/x' directory.  This helps determine if any of the builds failed/
# if there packages missing.
# It's a bit clunky, but we love it :)
#
# Build numbers
# -------------
# You can set specific build numbers by creating the
# package name inside build-nums dir:
# echo 2 > build-nums/xinit
#
# The way build numbers are handled in Slackware ARM is that
# when building individual components (which is always the way
# unless you're starting a port from scratch), you:
#
# 1.  Check if there's a file with the package base name inside the 'build-nums' directory
#     and create one if there isn't.
#
# 2.  Adjust the build number -- either increasing it if it's a package rebuild,
#     or resetting it to '1' if it's a version update.
#
# The reason for this is that Slackware build numbers often differ from Slackware ARM
# since it takes a while to catch up, and there may have already been several
# rebuilds in Slackware before we even start looking at rebuilding the package.
#
# When dealing with an Xorg update in Slackware, the easiest way to do it (without
# running the entire KDE.SlackBuild), is to:
# - Filter only the x updates from the ChangeLog entries
# - Grep "Removed" note down which exist for ARM, and paste those .tgz file names into
#   Slackware ARM's changelog.
# - Grep "Rebuilt" and add those to this script
# - Grep "Added" and add those to the "Upgraded" (since the script handles them the same)
# - Grep "Upgraded", as below:
# cat /tmp/f | grep Upgraded | sed 's?+x/??g' | cut -d: -f1 | rev | cut -d- -f4- | rev | while read updpkg ; do echo "$updpkg \\" ; done
# The first time, run this script WITHOUT updating build numbers - just to get everything
# upgraded and on the live filesystem.
# Run again, without updating version numbers to ensure everything links against each other
# For the Rebuilt packages, build those by supplying the "R" option to the "build" function
# For Upgraded packages, build those with the U option.
