+USAGE: lampadasql command { language }
+
+   This will pipe the file <command> together with each <language>
+   through the m4 macro processor. The suffix '.m4' will be appended
+   if not present.
+
+   If no value for <language> is given, the first two letters of variable
+   \$LANG are used. Right now that would be $DEFAULT_LANG.
+
+   Typically the output of lampadasql is further piped into /usr/bin/psql
+   to execute SQL statements:
+
