r"""Combine all sheets referred to a given CSS *proxy* sheet
|
||
|
|
into a single new sheet.
|
||
|
|
|
||
|
|
- no ``url()`` values are adjusted so currently when using relative references
|
||
|
|
for e.g. images it is best to have all sheets in a single folder
|
||
|
|
- in @import rules only relative paths do work for now but should be used
|
||
|
|
anyway
|
||
|
|
- messages are send to stderr
|
||
|
|
- output to stdout.
|
||
|
|
|
||
|
|
Example::
|
||
|
|
|
||
|
|
csscombine sheets\csscombine-proxy.css -m -t ascii -s utf-8
|
||
|
|
1>combined.css 2>log.txt
|
||
|
|
|
||
|
|
results in log.txt::
