PackageDev provides syntax highlighting and other helpful utility for Sublime Text resource files.
Resource files are ways of configuring the Sublime Text text editor to various extends, including but not limited to: custom syntax definitions, context menus (and the main menu), and key bindings.
Thus, this package is ideal for package developers, but even normal users of Sublime Text who want to configure it to their liking should find it very useful.
Install the package using Package Control. The package's name is PackageDev.
PackageDev was made for Sublime Text 3. An older unmaintained version can still be installed for Sublime Text 2, however.
