 664 Remote helper programs are invoked by Git to handle network transport.  This
 665 helper handles @code{gcrypt:} URLs that access a remote repository encrypted
 666 with GPG, using our custom format.
 667
 668 Supported locations are local, @code{rsync://} and @code{sftp://}, where the
 669 repository is stored as a set of files, or instead any Git URL where gcrypt
 670 will store the same representation in a Git repository, bridged over arbitrary
 671 Git transport.
 672
 673 The aim is to provide confidential, authenticated Git storage and
 674 collaboration using typical untrusted file hosts or services.")
