 To build a Debian package for Capstone, run the script, where `<tag-name>` is going to be the version 
 attached to both the `capstone.pc` file and the Debian package itself. The version is expected to be compliant with Debian versioning (a major/minor/patch), e. g. `5.0.4`. Debian versions can also support values to indicate pre-release, e. g. `6.0.0-Alpha1`.
 
-Note if a value such as `6.0.0-Alpha1` is provided, the major/minor/patch number is extracted for `capstone.pc`, which would have version `6.0.0`, but the Debian package would have the full version name on the control file.
