=head1 NAME

ExportEnv - Exports the environment from which a component release was made.

=head1 SYNOPSIS

  exportenv [options] <component> <version>

options:

  -h  help

  -f  force export overwriting if necessary

  -r  use FTP reconnect and resume transfer mode

  -v  verbose output (-vv very verbose)

  -d  dummy run (don't do anything) - assumes -v

  -e  exclude source

  -x  examine: confirm correct sizes of files on remote site rather than exporting them

=head1 DESCRIPTION

When a release is made, a description of the environment it was made from is stored with it. 

C<ExportEnv> takes a component name and version number, reads the environment data for this 

component and builds a list of component names and version numbers. It then encrypts these releases before sending them to the projects shared archive on a remote site.

Using the C<-f> option will force releases to be exported even if they already exist on the remote site (this only applies to components existing in the users export table)

If the C<-r> option is used and the FTP connection is dropped during the upload of a release, the tools will automatically reconnect to the FTP site and resume the upload. This feature may not be supported by some FTP servers.

Using C<-e> option will create a release without source. 

=head1 KNOWN BUGS

None
