=head1 NAME
GetEnv.pm - Provides an interface for installing and upgrading environments.
=head1 INTERFACE
=head2 GetEnv
Expects to be passed an C<IniData> reference, a reference to a hash containing the required component release versions, a flag indicating if to install source, a source install path (which may be undefined), a flag indicating if to overwrite source, a flag indicating whether there are components to be excluded or not and a verboisty level. Installs the specified component releases by adding, removing and upgrading existing components as required.
=head2 GetEnvFromRelData
Expects to be passed an C<IniData> reference, a component name, a version, a flag indicating if to install source, a source install path (which may be undefined), a flag indicating if to overwrite source, a flag indicating whether there are components to be excluded or not and a verboisty level. Retreives the version information associated with the specified component release version, and calls C<GetEnv> to install them.
=head1 KNOWN BUGS
None.
