well if you are packaging up pose files to apply the mat poses you are making set them up in the same manner you would find another type you have the runtime/libraries + textures

in your textures folder put a folder for your testures and place them in there

in the libraries put a pose folder then in there put a folder that indicates your mat poses and inside that put your mat poses

make sure you save your mat poses and textures after you have your setup ready or save them in your runtime and mimic the folders outside your runtime to put the files in

oh yeah and remember if you are going to change the names of any of the files to resave the mat poses again before copying them to the outer runtime folder for packaging.  then take your zip program and add to archive then rename the archive to what you want it to be so people know the product and zip it

then open your zip ( not extract) to double check everything is in there
