This documentation is shared by most Adacore packages.
Please replace PKG with gnatcoll-core.
The Debian package is named libgnatcoll.

Upstream use three versioning schemes.
* Commercial releases are numbered YY.MINOR,
  where YY contains the two last digits of the year (since 2017).
* Builds between 17.2 and 12.3 are numbered 12.3w (as wavefront).
* Every year, a GPL release without the GCC Runtime Library Exception
  is numbered as gpl-20YY.
There is no ordering implied between gpl-20YY and any YY.MINOR.
Upstream history is visible at https://github.com/AdaCore/PKG/network.
The version number is always visible in first line of ./configure.in.

When packaging a new version for Debian:

Download GPL release pristine archive from the Homepage URL field in
the control file.  Tracking upstream releases automatically is of
little interest, and quite hard as the website is modified each year.

Repackage it without generated files.
# mk-origtargz --repack --compression=xz --version=YY ../PKG-gpl-YYYY-src.tar.gz
