 645 repositories encrypted with GnuPG.  It works with the standard Git transports,
 646 including repository hosting services like GitLab.
 647
 648 Remote helper programs are invoked by Git to handle network transport.  This
 649 helper handles @code{gcrypt:} URLs that access a remote repository encrypted
 650 with GPG, using our custom format.
 651
 652 Supported locations are local, @code{rsync://} and @code{sftp://}, where the
 653 repository is stored as a set of files, or instead any Git URL where gcrypt
 654 will store the same representation in a Git repository, bridged over arbitrary
 655 Git transport.
 656
 657 The aim is to provide confidential, authenticated Git storage and
 658 collaboration using typical untrusted file hosts or services.")

1486 vc-dwim is a tool that simplifies the task of maintaining a ChangeLog and

1488 when a file change has been described in the ChangeLog but the file has not

1490 standards-compliant ChangeLog entries based on the changes that it detects.")

2137 which performs an incremental merge between two branches.  Its two primary
2138 design goals are to reduce the pain of resolving merge conflicts by finding
2139 the smallest possible conflicts and to allow a merge to be saved, tested,
2140 interrupted, published, and collaborated on while in progress.")
