The blessed (Python) package to manage your versions by scm tags (source files)
setuptools_scm_source-10.0.5-1-source
'setuptools-scm' extracts Python package versions from 'git' or 'hg' metadata instead of declaring them as the version argument or in a Source Code Managed (SCM) managed file.
Additionally, provides 'setuptools' with a list of files that are managed by the SCM (i.e. it automatically adds all the SCM-managed files to the sdist).
