# This script is installed as a module in
# /usr/share/vo-support/module/vomsdir.sh

# It is normally run by %post or %preun scriptlets in RPM packages
# for each installed VO. The first argument is the main command.
# Commands understood by this script are:
#     configure [list of VOs to add]
#     deconfigure [list of VOs to remove]
#
# Other commands are silently ignored. The list of VOs may be empty.
#
# The configure command will install the VO's .lsc file(s) in
# $X509_VOMS_DIR/$vo/
# from /usr/share/vo-support/vos/$vo/.
# The default if X509_VOMS_DIR is not set is to use
# /etc/grid-security/vomsdir/
#
# The deconfigure command will uninstall these files.
