According to PEP263 (http://www.python.org/peps/pep-0263.html

) the source code
encoding, like the magic comment '-*- coding: utf-8 -*-', must be on the two
first lines. If not, default encoding is ascii and SyntaxError will be raised
if there is a non-ASCII character.

this produce false result when filtering by search dir in select_image

is -s "local local-testing" list

will list repository nammed testing.

We use current locale to convert argv to unicode and handle it as uncode after.

If we have to format (aka interpolatation) we need to be sure this have to be
done in unicode and not in ascii. This avoid unicode error with ascii string
encoded in utf-8.

Example of failure between a string and an object

b = Exception(u"é")
Exception("error: %s" % b)
 => Exception("error: %s" % str(b)
 => UnicodeEncodeError: 'ascii' codec can't encode character u'\xe9' in position 0: ordinal not in range(128)

Before this, timeout only apply to repository caching.

Now timeout is used by all transfert functions.
A new parameter repo_timeout is available to set a custom timeout on repository

command extract use only one image at a time

min and max is no more handled by select_images

this allow to run parser script without running setup script
useful to valid arguments without causing trouble

this options are also settable by config
allow to have installsystems niced before launch action

python-psutil minimun version is 0.2.1 to support set_ionice

move command now ask for a global move and check if source repository are local

All command now use select_image in repoman to select which image should be
select for use

search is now added to repoman and not by command

best option was dropped for all command

changelog command take now more than one image
diff command is no more limited to 2 args. Can be one with globbing
list -a is dropped, use *:* instead (this can be used in all command)

is command allow smart image selection like this:

- ftp/* => list all image in repo ftp
- ftp/*:4 => list all image in version 4 in repo ftp
- *:4 => list all images at version 4 in search path
- */*:4 => list all images at version in all repo
- debian => list all images nammed debian in search path
- debian* => list all images starting by debian in search path
