assetutil process asset catalog .car files

assetutil [-ViotshMgpTZ] inputfile

assetutil processes a .car file generated from a image catalog removing requested scale factors, device idioms, subtypes, performance and memory classes. When thinning scale, idiom, subtype, performance, memory, and graphicsclassfallbacks can be given multiple times, the resulting file will contain all of the assets that match all of the parameters given. If scale, idiom, subtype and graphics class are given in one set, the same parameters must all be present in the subsequent set of parmeters. (IE the count must match)

A list of flags and their descriptions:

version information for assetutil
Produce a JSON description of the asset catalog object with the given name to --output directory if given or to stdout if no output path given. If no name is provided, report on the contents of the entire car file.

Idiom to keep. Can be one of universal/phone/pad.
Subtype to keep (integer)
Main Assets.car file used to supply the names of the assets to the -I (--info) and the dump options -d (--dump) and -D (--dump-stack).
Output file name, if no output file is given then input file is overwritten.
compare thinning attributes ´scale=2:idiom=phone:memory=2:graphicsclass=MTL1,2/scale=2:idiom=phone:memory=1:graphicsclass=MTL2,2´ will print to stdout if the files was thinned with the above thinning attributes, would the same Asset file result in both cases.
given a comma separated list of names, any assets in the car file that match one of the given names are preserved. Names are compared case insensitivly Name == name, uses the -o --output file to save the resulting .car file.
do an integrity check of the input file.
