+# Clones and checkout TF-M related repositories in case these are not present
+# under SHARE_FOLDER, otherwise copy the share repositories into current folder
+# (workspace)
+
+#
+# The way it works is simple: the top level job sets the SHARE_FOLDER
+# parameter based on its name and number on top of the share
+# volume (/srv/shared/<job name>/<job number>) then it calls the clone
+# script (clone.sh), which in turn it fetches the repositories mentioned
+# above. Jobs triggered on behalf of the latter, share the same
+# SHARE_FOLDER value, and these in turn also call the clone script, but
+# in this case, the script detects that the folder is already populated so
+# its role is to simply copy the repositories into the job's
+# workspace. As seen, all jobs work with repositories on their own
+# workspace, which are just copies of the share folder, so there is no
+# change of a race condition, i.e every job works with its own copy. The
+# worst case scenario is where the down-level job,
+# i.e. tf-m-build-config, uses its default SHARE_FOLDER value, in this
+# case, it would simply clone its own repositories without reusing any
+# file however the current approach prevents the latter unless the job
+# is triggered manually from the buider job itself.
