Enables tokenized header files to get prepended after minimization steps (and also saves you from having to type the same copyright crap at the top of each file).
anvil will install this plugin during post-install.
Assumes that your header files will be named header and that the extension of the header file will control which kinds of files the header applies to.
By convention, a header file at the very top of your repository will get applied to all files in your source tree that have a matching extension.
After that, header files within a directory will apply to all files found in that directory and 'override' any headers found at a higher level of the source tree hierarchy.
If you need to target a specific file you can provide the following configuration:
"anvil.headers": {
"headers": {
"relative/path/to/your/file.ext": "relative/path/to/your/header.ext"
}
}
