some kind of regexp functionality in pattern?

Tested with "4 Non Blondes":

Traceback (most recent call last):
...
File "/usr/local/lib/python2.6/site-packages/ArrangeMusic/arranger.py", line 68, in __init__
self.first_letter = c
NameError: global name 'c' is not defined

check config for initial-of-number.

rename to pattern and patternname

rewrite to use str.endswith and str.startswith

Add note: only used when album/track is set.
Add {artiststyle}: only used when {article} is set? (to make {artist}, {article} possible)

or think about some conditionals in format…?

add {article}, {theartist} (with article) and {artist} (w/o article) to substitution patterns

remove lettuce features or add README: ‘just 4 fun’

rethink modules, merge singleton to config…

put Arranger to arranger.py, rest of processing.py to tools

perhaps put Configuration and Cmdlineparser to their own modules

remove it, always add the source extension

this option should be removed, always do article ignoring

write installation, usage and configuration description

notice user that cmdline given pattern does not exist, and another one is used (should not be an error, just information)

create artistsplit[] in arranger initialization.
use in rename pattern: {artist1} {artist3} etc.
what to do when words in pattern exceeds length of artistsplit[]?

user should put it in another pattern, using it only when he knows, what artist it'll be used on. like:
[singer-pattern]
newpath={artist2}, {artist}/{album}/{title}

The {initial} must have the same functionality:
{initial2} == first letter of second artist word. so:

[singer-pattern]
newpath = {initial2}/{artist2}, {artist1}/{album}/{title}
