alphabetic order. This is best done with a text editor. Typical usage
order would be:
pgfixinclude
pgcompinclude
pgrminclude /src/include
pgcompinclude
pgfixinclude
sort include references
run multiple times:
pgcompinclude
pgrminclude /src/include
pgrminclude /
pgcheckdefines
There is a complexity when modifying /src/include. If include file 1
includes file 2, and file 2 includes file 3, then when file 1 is
processed, it needs only file 2, not file 3. However, if later, include
file 2 is processed, and file 3 is not needed by file 2 and is removed,
file 1 might then need to include file 3. For this reason, the
pgcompinclude and pgrminclude /src/include steps must be run several
times until all includes compile cleanly.
