12 This script generates precompiled headers for a given
15 Given a gmake makefile that belongs to some LO module:
16 1) Process the makefile to find source files (process_makefile).
17 2) For every source file, find all includes (process_source).
18 3) Uncommon and rare includes are filtered (remove_rare).
19 4) Conflicting headers are excluded (filter_ignore).
20 5) Local files to the source are excluded (Filter_Local).
21 6) Fixup missing headers that sources expect (fixup).
22 7) The resulting includes are sorted by category (sort_by_category).
23 8) The pch file is generated (generate).
