# This script is similar to the redhat-annobin-plugin-select.sh script which
# is part of the redhat-rpm-config package. That scripts decides between two
# versions of the annobin plugin for the system compiler and stores it choice
# in a symlink in the /usr/lib/rpm/redhat directory. The choice eventually
# resolves into the system gcc attempting to load either a plugin called
# annobin.so or a plugin called gcc-annobin.so.
# In a GTS environment the choice made by redhat-annobin-plugin-select.sh
# might not be appropriate (or even possible). The choice cannot be changed
# because the system compilation environment must remain instact. So instead
# the GTS versions of gcc and annobin install plugins called gts-annobin.so
# and gts-gcc-annobin.so (into the GTS gcc's plugin directory) and this script
# creates a pair of symlinks called annobin.so and gcc-annobin.so. In this
# way the decision made by redhat-annobin-plugin-select.sh is overridden
# without affecting any system files.
# We cannot be sure that this script will run inside a GTS enabled shell,
# so we have to use absolute paths.
