 668 Remote helper programs are invoked by Git to handle network transport.  This
 669 helper handles @code{gcrypt:} URLs that access a remote repository encrypted
 670 with GPG, using our custom format.
 671
 672 Supported locations are local, @code{rsync://} and @code{sftp://}, where the
 673 repository is stored as a set of files, or instead any Git URL where gcrypt
 674 will store the same representation in a Git repository, bridged over arbitrary
 675 Git transport.
