-# Selectively preprocess #ifdef / #ifndef statements.
-# Usage:
-# ifdef [-Dname] ... [-Uname] ... [file] ...
-#
-# This scans the file(s), looking for #ifdef and #ifndef preprocessor
-# commands that test for one of the names mentioned in the -D and -U
-# options.  On standard output it writes a copy of the input file(s)
-# minus those code sections that are suppressed by the selected
-# combination of defined/undefined symbols.  The #if(n)def/#else/#else
-# lines themselfs (if the #if(n)def tests for one of the mentioned
-# names) are removed as well.
-
-# Features: Arbitrary nesting of recognized and unrecognized
-# preprocesor statements works correctly.  Unrecognized #if* commands
-# are left in place, so it will never remove too much, only too
-# little.  It does accept whitespace around the '#' character.
-
-# Restrictions: There should be no comments or other symbols on the
-# #if(n)def lines.  The effect of #define/#undef commands in the input
-# file or in included files is not taken into account.  Tests using
-# #if and the defined() pseudo function are not recognized.  The #elif
-# command is not recognized.  Improperly nesting is not detected.
-# Lines that look like preprocessor commands but which are actually
-# part of comments or string literals will be mistaken for
-# preprocessor commands.
