+# @FUNCTION: version_format_string
+# @USAGE: <format> [version]
+# @DESCRIPTION:
+# Reformat complicated version strings.  The first argument is the string
+# to reformat with while the rest of the args are passed on to the
+# get_version_components function.  You should make sure to single quote
+# the first argument since it'll have variables that get delayed expansion.s
+# @EXAMPLE:
+# P="cow-hat-1.2.3_p4"
+# MY_P=$(version_format_string '${PN}_source_$1_$2-$3_$4')
+# Now MY_P will be: cow-hat_source_1_2-3_p4
