--- Comment #22 from Myron Walker <myron.walker at gmail dot com> --- It does the same things a gcov and lcov combined but in python. It also does merging of data but in a different way than gcov-tool. I might need to change that. Another part of it is to allow access to different types of resource location hinting. so a gcov prefix for a source code might be a github url and token. A gcno file hint might be a web url or sub or nfs share. Like wise the data file hints might be http, smb or nfs prefixes. https://github.com/myronww/pycover Still a work in progress though.
