#note to self. paste list of supported models into first line of empty README.models
#file. run sh ./fixrm to spread the model list evenly over as many lines as needed
#also upload source to slackbuildsdirectlinks, as epson keeps changing the url
#of their own download link.

#note: for some reason, epson's versioning went from 1.2.15 to 1.2.18 to 1.2.17
#just in case anyone is confused, blame epson :-) !!!
