Error: Invalid version string
#############################

|bpt| stores version numbers in a type-safe manner, and all version numbers
are required to match `Semantic Versioning <https://semver.org>`_.

If you see this error, it means that a |bpt| found a version number that does
not correctly conform to Semantic Versioning's requirements for version numbers
refer to the |bpt| output for a description of *where* the bad version string
was found, and refer to the Semantic Versioning website for information about
how to properly format a version number.

In addition to requirements on individual versions, providing a version range
requires a slightly different syntax.
