+# Universal Configuration Generator. - A working title.
+
+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.
+
+## Examples
+
+Let statements introduce a new name in a ucg file. Most configurations
+will be a tuple like below. Tuples are delimited by braces and have a list
+of named fields in them.
+
+    let mysql_conn_base = {
+      host = "db1.local.net",
+      port = 3306,  // knows the difference between strings and numbers.
+      database = "place-holder",
+    };
+
+You can use a previously defined tuple as the basis for a new tuple. Doing
+this will make a copy of the source tuple and allow you to add new fields
+or override an already existing field.
+
+    let mysql_app_conn = mysql_conn_base{
+       database = "appdb",
+       timeout = 30,
+    };
+
+Types are inferred for tuple fields. We enforce type consistency when
+overriding a field in a base tuple. The port field below expects a
+number not a string so you will get a TypeFail error.
+
+
+    let bad_mysql_conn = mysql_conn_base{
+       port = "3307",
+     }
