+# parabola changes and rationale:
+# Several Parabola packages depends on ICU, and the ICU soname changes often.
+#
+# This means that if we don't rebuild all the Parabola packages that depends
+# on ICU as soon as the new Arch Linux, Arch Linux 32 and Arch Linux ARM ICU
+# packages are synchronized into the Parabola repositories, we have an issue.
+#
+# At the time of writing, the synchronization is automatic and can happen at
+# any time.
+#
+# At first nothing was done to fix or workaround that issue. In practice,
+# once a new ICU was synchronized, many users were upgrading before the
+# Parabola packages had the time to be rebuilt. For such users, it silently
+# broke all the installed Parabola packages that were depending on the old ICU.
+# This means that users had to find a way to downgrade packages manually or wait
+# until developers would finally have rebuilt all the packages that were broken.
+#
+# Then such packages were modified to make them depend on the exact version of
+# the ICU packages they were built against. This way, once the new ICU package
+# was synchronized, users could not upgrade if they had packages that were not
+# rebuilt yet against the new ICU packages as their dependencies could not be
+# met anymore if the ICU would have been upgraded.
+# However this workaround prevents installing packages that depends on the new
+# ICU if you have packages that depends on the old ICU. It also prevent users
+# from upgrading their system when that occurs.
+#
+# The correct fix would probably be to automatically build all the Packages
+# instead of relying on Arch Linux Packages. The synchronization could then be
+# done (semi-)automatically at a source level.
+#
+# However we don't have the code, configuration and/or infrastructure to run
+# an automatic builder for all packages yet even if there is work in this
+# direction.
+#
+# In the meantime, this version of ICU is meant to enable Parabola packages to
+# link against it. This enables all the Parabola packages to depend only on this
+# ICU version while the packages coming from upstream distributions would only
+# depend on that distribution's ICU.
+#
+# The downside of this workaround is that it consumes more resources and it
+# doesn't scale: If we want to avoid all the breakages introduced by that issue
+# we would then need to have a Parabola version of all the dependencies of the
+# Parabola packages, which has many issues:
+# - It would increase the work of Parabola maintainers as we would need to
+#   manually sync with upstream and build the PKGBUILDs of each dependency.
+# - Without compression or deduplication, such libraries would use twice the
+#   amount of storage, or even RAM if two programs depending on two different
+#   version of the library are running at the same time.
+#
+# So the idea is to only use it for libraries that often have this issue.
+#
+# Changes:
+# - Changed the configure prefix (to enable both libraries to be installed in
+#   parallel)
+# - Added icu-parabola.conf and a .install to run ldconfig after installation in
+#   order to take into account the path of this library version.
