rbrito / pkg-pdfsizeopt Goto Github PK

If I run the command ./pdfsizeopt ./small1.pdf, I get the error :

With Python2 on the way out in the next several years, what does the upgrade path look like for Python3?
I am somewhat knowledgeable in Python, but it would be nice to know what I can expect before I start trying to port pdfsizeopt to Python3.
