/*
 * A day in the life of a network operation
 * ========================================
 *
 * The library gets told to ls-remote/push/fetch on/to/from some
 * remote. We look at the URL of the remote and fill the function
 * table with whatever is appropriate (the remote may be git over git,
 * ssh or http(s). It may even be an hg or svn repository, the library
 * at this level doesn't care, it just calls the helpers.
 *
 * The first call is to ->connect() which connects to the remote,
 * making use of the direction if necessary. This function must also
 * store the remote heads and any other information it needs.
 *
 * If we just want to execute ls-remote, ->ls() gets
 * called. Otherwise, the have/want/need list needs to be built via
 * ->wanthaveneed(). We can then ->push() or ->pull(). When we're
 * done, we call ->close() to close the connection. ->free() takes
 * care of freeing all the resources.
