+# Build the DebugCmdConstants.h and DebugCmdInfoConstants.cc files from the

+# We do this via a script rather than maintaining them directly because
+# the struct is a little complicated, so has to be initialized from code,
+# plus we want to make adding new constants somewhat less painful.
+#
+# The input filename should be supplied as an argument.
+#
+# DebugCmds are printed to DebugCmdConstants.h
+# DebugCmdInfos are printed to DebugCmdInfoConstants.cc
+#
+# The input format is:
+#
+#	cmd: [DebugCmd]
+#	names: [space delimited names of cmd]
+#	resume: ['true' or 'false': should execution resume after this command?]
+#	help: [some help text]
+#
+# Blank lines are skipped.
+# Comments should start with // and should be on a line by themselves.
