Documentation/remote-helpers: Rewrite description
Rewrite the description section to describe what exactly remote
helpers are and the need for them. Also mention the curl family of
remote helpers as an example.
[jc: with readability fixes from Jonathan squashed in]

Various particular -helper programs will behave as documented here. +Remote helper programs are normally not used directly by end users, +but they are invoked by git when it needs to interact with remote +repositories git does not support natively. A given helper will +implement a subset of the capabilities documented here. When git +needs to interact with a repository using a remote helper, it spawns +the helper as an independent process, sends commands to the helper's +standard input, and expects results from the helper's standard +output. Because a remote helper runs as an independent process from +git, there is no need to re-link git to add a new helper, nor any +need to link the helper with the implementation of git. + +Every helper must support the "capabilities" command, which git will +use to determine what other commands the helper will accept. Other +commands generally concern facilities like discovering and updating +remote refs, transporting objects between the object database and +the remote repository, and updating the local object store. + +Helpers supporting the 'fetch' capability can discover refs from the +remote repository and transfer objects reachable from those refs to +the local object store. Helpers supporting the 'push' capability can +transfer local objects to the remote repository and update remote refs. + +Git comes with a "curl" family of remote helpers, that handle various +transport protocols, such as 'git-remote-http', 'git-remote-https', +'git-remote-ftp' and 'git-remote-ftps'. They implement the capabilities +'fetch', 'option', and 'push'. COMMANDS -------- |
