| [![Castle Game Engine logo with title](https://castle-engine.io/wp/wp-content/uploads/2019/07/cge_logo_with_text-200x238.png)](https://castle-engine.io/wp/wp-content/uploads/2019/07/cge_logo_with_text.png "Castle Game Engine logo with title") | Our [build tool](https://github.com/castle-engine/castle-engine/wiki/Build-Tool) got a few minor improvements/fixes lately: - Build tool now supports `executable_permission` attribute to package some additional files with Unix executable bit set. In general useful by applications that have more than 1 executable. Used now by [view3dscene manifest](https://github.com/castle-engine/view3dscene/blob/master/CastleEngineManifest.xml) so that it packages `tovrmlx3d` binary with executable permissions. - Build tool now warns if you try to use absolute path in search\_paths in [CastleEngineManifest.xml](https://github.com/castle-engine/castle-engine/wiki/CastleEngineManifest.xml-examples) . This is almost always a mistake, you want to use relative paths. - Many updates to [CastleEngineManifest.xml docs](https://github.com/castle-engine/castle-engine/wiki/CastleEngineManifest.xml-examples). - Fixes to `castle-engine generate-program`. - Various improvements to our `Makefile` and [Jenkins](https://github.com/castle-engine/castle-engine/wiki/Cloud-Builds-(Jenkins)) to just rely on the build “all across the board” and not use some shell scripts.
