# Update the include file with the dates of the .pot files.
+# (Note all the $ signs have to be doubled to get them past make's expansion.
+# This passes single $ signs to the shell, where some of them have to be
further
+# escaped with \ characters in order to get them into the .inc file.
+# The extraction of the dates relies on a shell that does command substitution
+# using bash's $() syntax, which runs the command within the (), so may not
+# work with all shells.)
+# The variables with a single $() are Makefile variables which get expanded
+# right at the beginning so their expanded values are used in the commands.
