 =head1 NAME

 B<openpkg release> - OpenPKG Release Utility

 =head1 SYNOPSIS

 B<openpkg release> [B<-F>|B<--fmt> I<format>]

 =head1 DESCRIPTION

 The B<openpkg release> command displays the OpenPKG release tag and

 distribution URL. The release tag uniquely identifies an OpenPKG

 distribution and the distribution URL is the location where the

 distribution packages and indices are stored.

 =head1 OPTIONS

 =over 4

 =item B<-F>, B<--fmt> I<format>

 The output format specification. The argument I<format> is an arbitrary

 string which can contain the special expansion constructs "C<%t>" for

 expanding the release tag, "C<%u>" for expanding the distribution URL

 and "C<\n>" for expanding an embedded newline character.

 The instance UUID information is also availble by expanding

 C<%r> to UUID_REGISTRY, C<%i> to UUID_INSTANCE, C<%p> to UUID_PLATFORM.

 The default I<format> is "C<OpenPKG-%t %u>".

 =item B<-r>, B<--release> I<release>

 The package "C<Release>" header value to use for deriving the release

 tag. The values in the F<@l_prefix@/etc/openpkg/release> file and the

 "C<Release>" header of the bootstrap package B<openpkg> are ignored if

 this option is used.

 =head1 FILES

 =item F<@l_prefix@/etc/openpkg/release>

 This optional configuration file can be used to explicitly set values

 for the OpenPKG release tag and distribution URLs. It consists of lines

 with variable name/value pairs. The following configuration variables

 are recognized:

 =over 4

 =item B<TAG=>I<tag>

 The default I<tag> is automatically derived from the "C<Version>" header

 of the OpenPKG bootstrap package B<openpkg>. One usually only sets this

 explicitly to a value if a bootstrap package is used from a foreign

 distribution version.

 =item B<URL=>I<url>

 The fully-qualified distribution URL based on either the "C<ftp>",

 "C<http>" or "C<file>" URL schemes. If I<url> contains a trailing

 "C</*>", this is expanded according to the I<tag> value of the B<TAG>

 variable and the corresponding filesystem layout on C<download.openpkg.org>.

 The default I<url> is "C<http://download.openpkg.org/stacks/*>".
