Add version number in the log file

[amjjbonvin]

It would be good to print out in the log file at the start the version number of the used haddock3 installation
Will help in supporting users.

hi, I think the version number is already there:

##############################################
#                                            #
#                 HADDOCK 3                  #
#                                            #
##############################################

Starting HADDOCK 3.0.0 on 2023-08-29 11:31:00

As we are doing continuous integration with (+-) daily merges, should we somehow add the full last merge git SHA (or just the first 6 characters) next to the version ?
Because for now, the 3.0.0 is kind of hard coded, and never automatically updated.

that would be nice..even better would be to have the commit ID..but I honestly don't know whether it's doable

Could use https://pypi.org/project/setuptools-scm/ to determine the version from git (tags).

Indeed !
an other branch autamatic-patch-update2 is using this setuptools-scm approach.
But it generate natsy patch identifiers !
