On version.i generation, check the content of the following files : * "extra_version_name" The first line is used to populate the EXTRA_VERSION_NAME pre-processor define statement. * "extra_version_description" The content is used to populate the EXTRA_VERSION_DESCRIPTION pre-processor define statement. It should contain the description of local modifications done to the tree. This can be used by distribution packager to specify what changes were applied locally. Mostly in the form of patch/commit name. All non-alpha numeric characters are converted to "-".
