+# It checks, 'installs', and 'distributes' the last gpc1 MySQL dump.
+# The main steps are the following:
+# 1) Check if a checksum file is available
+#    - if it is not, the script sleeps $SLEEPING_TIME seconds, and
+#      iterates up to $MAX_ITERATIONS times.
+# 2) Check the gpc1 dump file against its checksum.
+# 3) Import gpc1 into gpc1_0 or gpc1_1 (ensured by gpc1Import.py utility)
+# 4) Distribute the validated files, that is:
+#    - Hard-links the gzipped MySQL dump in the distribution directory
+#    - Moves the MD5 checksum to the distribution directory
