# Universal Configuration Grammar.
This is an experiment in configuration management. The approach is **not**
to create a "parsable" config file format. We have plenty of
those. Instead we try to specify a grammar for describing
configuration values that can then target various configuration
formats to output to.
In theory this could support anything from command line flags to json
to yaml or toml or even xml.
The goal is to allow a global shared configuration repository that can
be version controlled, enforce _some_ typesafety, and output
configuration for any application regardless of that applications
preferred format.
## The Usual Warnings
This is still very much an experiment and the language and api can be expected
to change and mutate. It also probably has bugs and isn't yet the most user
friendly language and compiler to use. You have been warned.
## Usage
You can get ucg with cargo `cargo install ucg`.
Running ucg help will show the following output.
```sh
Universal Configuration Grammar compiler.
USAGE:
ucg [SUBCOMMAND]
FLAGS:
-h, --help Prints help information
-V, --version Prints version information
SUBCOMMANDS:
build Compile a specific ucg file.
help Prints this message or the help of the given subcommand(s)
validate Check a specific ucg file for errors.
```
