unifdef - selectively remove C preprocessor conditionals

Written by Tony Finch <[email protected]> - https://dotat.at/prog/unifdef/

The unifdef utility selectively processes conditional C preprocessor
#if and #ifdef directives. It removes from a file both the directives
and the additional text that they delimit, while otherwise leaving the
file alone.

Please see the INSTALL file for installation instructions.

Pre-formatted documentation can be found in unifdef.txt

You can download the latest release tar and zip files from:
	https://dotat.at/prog/unifdef

Note: GitHub's "releases" are incomplete and broken, but I am not
able to redrect them to the right place.

You can clone the development repository using:
	git clone https://dotat.at/git/unifdef.git

I also maintain a copy at https://github.com/fanf2/unifdef
(Warning: GitHub's zip download is incomplete and unusable.)
