 657 Remote helper programs are invoked by Git to handle network transport.  This
 658 helper handles @code{gcrypt:} URLs that access a remote repository encrypted
 659 with GPG, using our custom format.
 660
 661 Supported locations are local, @code{rsync://} and @code{sftp://}, where the
 662 repository is stored as a set of files, or instead any Git URL where gcrypt
 663 will store the same representation in a Git repository, bridged over arbitrary
 664 Git transport.
 665

 667 collaboration using typical untrusted file hosts or services.")
