+SUMMARY="Selectively remove C preprocessor conditionals"
+DESCRIPTION="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."
