"""Configuration that affects the behaviour of Bazaar.
21
Currently this configuration resides in ~/.bazaar/bazaar.conf
22
and ~/.bazaar/locations.conf, which is written to by bzr.
24
In bazaar.conf the following options may be set:
26
editor=name-of-program
27
email=Your Name <your@email.address>
28
check_signatures=require|ignore|check-available(default)
29
create_signatures=always|never|when-required(default)
30
gpg_signing_command=name-of-program
31
log_format=name-of-format
33
in locations.conf, you specify the url of a branch and options for it.
34
Wildcards may be used - * and ? as normal in shell completion. Options
35
set in both bazaar.conf and locations.conf are overridden by the locations.conf
37
[/home/robertc/source]
38
recurse=False|True(default)
40
check_signatures= as above
41
create_signatures= as above.
43
explanation of options
44
----------------------
45
editor - this option sets the pop up editor to use during commits.
46
email - this option sets the user id bzr will use when committing.
47
check_signatures - this option controls whether bzr will require good gpg
48
signatures, ignore them, or check them if they are
50
create_signatures - this option controls whether bzr will always create
51
gpg signatures, never create them, or create them if the
52
branch is configured to require them.
53
log_format - this option sets the default log format. Possible values are
54
long, short, line, or a plugin can register new formats.
56
In bazaar.conf you can also define aliases in the ALIASES sections, example
59
lastlog=log --line -r-10..-1
60
ll=log --line -r-10..-1
