This release has benefited from bug reports & queries from

Thank you!

Release notes below, under * Changles in 0.4 (since 0.3.1)

* From the README file

Guile Config is a library providing a declarative approach to application
configuration specification.  The library provides clean configuration
declaration forms, and processors that take care of:

- Configuration file creation
- Configuration file parsing
- Command-line parameter parsing using getopt-long
- Basic GNU command-line parameter generation (--help, --usage, --version)
- Output generation for (compiled from the configuration declaration):
  + --help and --usage
  + --version
- Automatic deduction of short-versions of argument names
- Support for arbitrarily nested subcommands
- Support for keyword parameters as well as positional parameters

* Changles in 0.4 (since 0.3.1)

** Improve documentation: explain `full-command'

   Rekado pointed out that `full-command' was currently not documented.  This
   is now fixed.

** Provide better error messages for end user

   This affects both validation error messages when someone runs a program
   using guile-config and handling of the --help message in the face of
   validation errors or missing mandatory fields.

Oh joy, oh joy!
