+# 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 which depend
+# on ICU, as soon as the new ArchLinux, ArchLinux32, and ArchLinuxARM ICU
+# packages are synchronized into the Parabola repositories, we have a problem.
+# The repo server synchronizes with the upstream repos un-attended; so this
+# is a wonderful surprise each time; and we hustle frantucally to get the
+# system sane again. We could watch the testing and staging repos of each
+# upstream, and start re-building everything in a Parabola staging repo;
+# but that could result in discarded work, if those exact versions are not the
+# ones which are eventually released into [core].
+#
+# 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
+# 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 package. However this workaround also prevents
+# installing packages that depends on the new ICU.
+#
+# The correct fix would probably be to automatically build all the Packages
+# instead of relying on Arch Linux Packages. Still, a staging repo would be
+# required to hold the new packages, until they all can be released together sanely.
+# 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 exists for Parabola packages to link against
+# at runtime. In this way, Parabola packages can depend only on the "sodeps" exposed
+# by ICU, which is usually provided by the upstream distribution's ICU; but may be
+# this ICU, if the Parabola package has yet to be rebuilt agianst the upgraded ICU.
+#
+# It is inspired by the admittedly awkward hack of versioned library
+# dependencies more commonly seen (e.g. in the AUR as 'icu65') on which
+# proprietary binaries built against Debian's ICU will depend. It is awkward,
+# in the eyes of the beholder and this elegantly scales to Parabola's needs,
+# without consuming increasing resources, which is the best definition of "not
+# awkward".
+#
+# To use it, simply add the following dependency to any package which parabola
+# has built or rebuilt:
+#
+#   depends=('libicui18n.so')
+#
+# or whichever shared library is reported by readelf -d /path/to/compiled/ELF/file
+# and, every time the upstream distribution upgrades ICU, update this package
+# as well, to ensure it always stays exactly one version behind.
+#
+# This works well for ICU, even for packages which link to both the older and
+# newer versions of libicu*.so, since ICU uses versioned symbols as reported by
+#
+#   nm -D --demangle --with-symbol-versions /path/to/library
+#
+# However, caution must be taken before implementing the same idea for other
+# libraries. So the idea is to only use it for libraries that often have this
+# issue.
+#
+# Changes:
+# - remove all files other than libicu*.so.*
+# - depend on icu; this is needed because if the package is installed on its
+#   own, ldconfig will create untracked symlinks which were supposed to be
+#   installed by the icu package.
