-## FIXME: including scripts/@ftp/module.mk fails.
-## Is that an automake bug?
-## Would getting the quoting character right fix it?
+## Automake fails to process "include scripts/@ftp/module.mk" in the directory
+## above.  All of the commands which would normally be in this file were
+## manually placed in scripts/module.mk to avoid using the "include" directive.
 ##
-## What should be in this file is in scripts/module.mk.
+## This is an Automake bug.  Automake has switched to a Perl backend which uses
+## the following pattern to detect a path:
+##
+## my $PATH_PATTERN = '(\w|[+/.-])+';
+##
+## This pattern only includes alphanumeric, '_', and [+/.-], but not "@".
