=head1 NAME

PullEnv - Copies a released environment from another archive.

=head1 SYNOPSIS

  pullenv [options] <component> <version> <remote-reltools-ini-file>

options:

  -h  help

  -f  if check fails, overwrite local copy

  -v  verbose output (-vv very verbose)

=head1 DESCRIPTION

If two sites that share a common WAN want to have separate local archives, the commands C<PushEnv> and C<PullEnv> can be used to keep them in sync. They are similar is spirit to C<ExportEnv> and C<ImportEnv>, however the files are copied directly rather than being encrypted and placed on a shared repository.

For each component in the specified external environment, checks to see if the corresponding release directory exists in the local archive. If it does, each if is checked to ensure its modified time and size is that same as in the external archive. If the check fails an error is thrown (by default, unless the C<-f> switch is used). If is does not, the directory is created and the component is copied into it.

=head1 KNOWN BUGS

None.
