%(bzrcmd)s - Bazaar next-generation distributed version control
217
Bazaar (or %(bzrcmd)s) is a distributed version control system that is powerful,
218
friendly, and scalable. Bazaar is a project of Canonical Ltd and part of
219
the GNU Project to develop a free operating system.
221
Bazaar keeps track of changes to software source code (or similar information);
222
lets you explore who changed it, when, and why; merges concurrent changes; and
223
helps people work together in a team.
229
.I "~/.bazaar/bazaar.conf"
230
Contains the user's default configuration. The section
232
is used to define general configuration that will be applied everywhere.
235
can be used to create command aliases for
236
commonly used options.
238
A typical config file might look something like:
243
email=John Doe <jdoe@isp.com>
247
commit = commit --strict
249
log10 = log --short -r -10..-1
