Some particularly interesting things in bzrlib are:
26
* bzrlib.initialize -- setup the library for use
27
* bzrlib.plugin.load_plugins -- load all installed plugins
28
* bzrlib.branch.Branch.open -- open a branch
29
* bzrlib.workingtree.WorkingTree.open -- open a working tree
31
We hope you enjoy this library.
