+Debug flags
+
+Run modeq with comma separated list of flags without spaces,
+"+d=flg1,flg2,..." where flg1,flg2,... are one of the strings on the
+leftmost column. Special flag named "all" turns on all flags.
+
+Each debug printing is done by giving a flag name to the print function, like:
+
+  Debug.fprint ("li", "Lookup information:...")
+
+If modeq is run with +d=foo,li,bar,etc this line will appear on
+stdout, not otherwise.  For backwards compatibility for debug prints
+not yet sorted, the old 
+
+  Debug.print 
+
+was changed to a call like
+
+  Debug.fprint ("olddebug",...)
+
+So if modeq is run with the debug flag "olddebug" (or "all"), these
+messages will appear. The calls to Debug.print should eventually be
+changed to appropriate flagged calls.
+
+'-' in front of a flag turns of that flag, i.e. d=all,-dump will turn on all flags 
+except dump.
