* Added groups selection work around code.
* Intended for use as a module to be imported by other scripts,
usually with "from groups import group_lists" or "from groups import
group_lines" or similar.
* Example to sign and encrypt a file.
* Similar to encrypt-file.py except all keys are considered trusted
and signs with the default key.
* Also encrypts to the default key.
* Example to encrypt a file to a single key.
* Takes key ID and/or fpr as a CLI parameter.
* Takes path and filename as a CLI parameter.
* Encrypts to specified key only, no signing and writes the output in
both ASCII armoured and GPG binary formats with output filenames
based on input filename.
* Added the same license as used with the HOWTO.
* Since these examples are so basic, they'll be dual licensed the same
as GPGME itself (otherwise it would slip too dangerously against the
need for permissive licensing of crypto libraries).
* Added reference to location where all the examples included in the
HOWTO will be available as executable scripts.
* Included a short README file in that location.
