### Guess version number (from tags)
## if there is a current tag and it is unique, take it as a version
## if not unique, take the one with numbers in it
## if several have numbers, take the smallest one by lexicographical order
## else, maybe take the previous one, if unique, and same rules if non unique/
## if no tag at all, create one called 0.1 (with git tag), and use it for "version"
