+# This script parses a command_table file into something which is a bit 
+# easier for an awk script to understand.
+#
+# Input syntax: a .ct file
+#
+# Output syntax:
+# (for the command_table line)
+#	command_table  <command_table>
+#
+#(for each request definition)
+#	BOR
+#	sub: <subroutine name>
+#	hlp: <help text>
+#	cmd: <command>
+#	opt: <option>
+#	EOR
+# (there may be more than one 'cmd' or 'opt' line
+#
+# A number sent to the output represents a parse error --- it will be 
+# followed by the next line which will have the form:
+#	ERROR: <error text>
+#
+# The design of this output syntax is such that it should be easy for
+# an awk script to parse.
+
+#
+# The first section of this script is just to canonicalize the file.  
+# It removes comments, and puts each command_table request onto a single
+# line
+#
