# 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

# In a GTS environment the choice made by redhat-annobin-plugin-select.sh

# 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.
