unifdef - selectively remove C preprocessor conditionals
Written by Tony Finch <dot@dotat.at> - 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

able to redrect them to the right place.
You can clone the development repository using:
	git clone https://dotat.at/git/unifdef.git
