+expand -- Expand tabs (EXTERNAL) [v1.1]
+          Written by Jeff Ding
+
+syntax:  expand <pathname> [-c<ascii number>] [-t<number>]
+                [-s"<tabstop 1,tabstop 2,tabstop 3,....,tabstop 16>"] 
+
+ex:      expand file.w.tabs
+         expand merlin.s -c160 -s"14,20,35"
+         > file.no.tabs ; expand file
+
+'Expand' expands up to 16 definable tab stops per line in the given
+pathname.  Line lengths of up to 255 characters are supported.  Longer
+lines are split into multiple lines.  Use output redirection on the
+command line to save output in a file (last example).  The second
+example works great for viewing Merlin source files.
+
+Options are as follows: 
+
+    -c: character for tab.  Enter the ascii value of the character
+        to use for the tab expansion.  The default character is value 9
+        for ctrl-I.  The tab character is hi-bit sensitive.
+
+    -t: tab spaces.  This is the number of spaces between two consecutive
+        tab stops, normally 8.  Can be any number from 1 to 255.
+
+    -s: tab stops.  Up to 16 tab stops can be defined manually.  Each stop
+        must be greater than the previous with no value exceeding 255.
+        If less than 16 stops are defined, the remaining stops are
+        constructed from the defined tab spaces.
