 Getting it to work:
 
 1. Go to the `rust` folder and run `cargo build --release`. (Note: the crate requires that it is inside of a Git repostory, otherwise it will fail to build. This may not be the case if you downloaded the source code from the Releases page. In that case, run `git init` to create a `.git` folder as a workaround)

+On macOS you're getting the ```dyld: Library not loaded: @rpath/libclang.dylib``` error during the build process.

+OS can't find ```libclang.dylib``` dynamic library because it resides in a non-standard path, set up the DYLD_FALLBACK_LIBRARY_PATH environment variable to point to the path where ```libclang.dylib``` can be found, e.g. for Command Line Tools:

 On Windows, when exporting I get an error similar to "Failed to save spritesheet as [name]; Access is denied (os error 5)."
 
 - Disable your virus scanner and try again. If you don't have a virus scanner enabled, you may not have permission to export into your selected folder (e.g. the Program Files folder may require admin privileges), so try exporting to your own users folder instead, or the Desktop, for example.
