"""Configuration that affects the behaviour of Bazaar.
20
Currently this configuration resides in ~/.bazaar/bazaar.conf
21
and ~/.bazaar/branches.conf, which is written to by bzr.
23
In bazaar.conf the following options may be set:
25
editor=name-of-program
26
email=Your Name <your@email.address>
27
check_signatures=require|ignore|check-available(default)
28
create_signatures=always|never|when-required(default)
29
gpg_signing_command=name-of-program
31
in branches.conf, you specify the url of a branch and options for it.
32
Wildcards may be used - * and ? as normal in shell completion. Options
33
set in both bazaar.conf and branches.conf are overriden by the branches.conf
35
[/home/robertc/source]
36
recurse=False|True(default)
38
check_signatures= as abive
39
create_signatures= as above.
41
explanation of options
42
----------------------
43
editor - this option sets the pop up editor to use during commits.
44
email - this option sets the user id bzr will use when committing.
45
check_signatures - this option controls whether bzr will require good gpg
46
signatures, ignore them, or check them if they are
48
create_signatures - this option controls whether bzr will always create
49
gpg signatures, never create them, or create them if the
50
branch is configured to require them.
51
NB: This option is planned, but not implemented yet.
