+# Building XPIDLs effectively consists of two steps:
+#
+#   1) Staging all .idl files to a common directory.
+#   2) Doing everything with the .idl files.
+#
+# Each .idl file is processed into a .h file and typelib information.
+# The .h file shares the same stem as the input file and is installed
+# in the common headers include directory.
+#
+# XPIDL files are logically grouped together by modules. The typelib
+# information for all XPIDLs in the same module is linked together into
+# an .xpt file having the name of the module.
+#
+# As an optimization to reduce overall CPU usage, we process all .idl
+# belonging to a module with a single command invocation. This prevents
+# redundant parsing of .idl files and significantly reduces CPU cycles.
+
+# For dependency files.
