+.BI "\-N\fP, \fB\-\-numeric"
+Instead of using temporary filenames similar to the input symbols, use numeric filenames such
+as t0002.c, etc. May be needed for systems which don't allow many similar long filenames, or
+for systems that tend to run out of argument space. Note, using this option
+implies "\-F\fP, \fB\-\-rebuild" - all packaging will be rebuilt every time pkgdata is run.
