USAGE="A simple wrapper for generating jpg pictures out of svg-files in parallel.
|
|
Usage: `basename $0` [-h] [-i] [-j nb_jobs] command arg_list
|
|
-h Shows this help
|
|
-c give the path to the cfg file
|
|
-i give the path of the svg files without the last /
|
|
-k chek if the jpg already exist
|
|
-b set the background to transparent
|
|
-s set the sleeptime while there are too many simultanious jobs
|
|
-j Set number of simultanious jobs. Default is 2
|
|
-o directory where the files should be moved to after creation.
|
|
Default ist PICCREATE_OUT
|
|
Examples:
|
|
`basename $0` -i file -c config
|
|
`basename $0` -j 3 -i file -c config"
