# A c-shell script that uses convdate, and walks all directories under
# your FSP home directory in order to find files that are out dated.
# It allows complete control of how long to leave files alone via 2
# files, .FSP_EXPIRE and .FSP_TIMEOUT. If neither of these two files
# exist, the directory is ignored, if either of them exist, every file
# in the directory is tested to see if it should be expired or timed
# out. Each of the two files contains one line containing an integer.
# This integer is the number of days after which a file should be
# expired or timed out. The .FSP_EXPIRE causes the script to check
# the current date against the last access (includes reads) time and
# if it's greater, remove it. The .FSP_TIMEOUT checks the last
# modified time and compares it to the date and if it has been around
# too long, to remove it.
