selectively remove C preprocessor conditionals

unifdef - selectively remove C preprocessor conditionals

Written by Tony Finch [email protected] - http://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: http://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 http://dotat.at/git/unifdef.git

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

Please send bug reports and patches to me via email to the address above. Unless you state otherwise, I will assume that any contributions are under the two-clause BSD licence. See the COPYING file for details.
