+# remove extra #include's
+
+# pgcompinclude must be run before and after pgrminclude. It must be
+# run before because we don't want include dependencies to leak into
+# the C program files, and after because removal of includes from headers
+# can cause new include unfulfilled dependencies.
+#
+# Limitations: 2011-09-24
+#
+# Pgrminclude, when processing header files, can cause includes to be
+# removed that require the addition of new illogical header files.
+# This is dependent on what order the header files are processed.
+# Manual review of header files now needed to satisfy pgcompinclude is
+# required.
+#
+# C program files that have #ifdef blocks that contain code that cannot
+# be compiled on the platform from which pgrminclude is run cannot be
+# processed, and are skipped.
