 Currently, installing python packages leads to a lot of notes at the end
 pointing to `port select`.
 {{{
   py38-codestyle has the following notes:
     To make the Python 3.8 version of pycodestyle the one that is run when
 you execute the commands without a version suffix, e.g. 'pycodestyle',
 run:

     port select --set pycodestyle pycodestyle-py38
   py38-flake8 has the following notes:
     To make the Python 3.8 version of flake8 the one that is run when you
 execute the commands without a version suffix, e.g. 'flake8', run:

     port select --set flake8 flake8-38
   py38-pyflakes has the following notes:
     To make the Python 3.8 version of py-pyflakes the one that is run when
 you execute the commands without a version suffix, e.g. 'pyflakes', run:

     port select --set pyflakes py38-pyflakes
 }}}
 However, I tend to have the respective ports already selected as the
 default version. So, I would either run `port select --set` although it is
 not necessary, or first do a `port select --list` to check the current
 status.

 The latter should be possible to automate – it would be great if the
 output would already indicate the current setting, so that users have all
 necessary information at hand to determine whether they should take action
 or not.  Something like:
 {{{
   py38-flake8 has the following notes:
     The Python 3.8 version of flake8 is already port selected to be run
 when you execute the commands without a version suffix. (Use "port select
 --list flake8" to change.)
   py38-pyflakes has the following notes:
     To make the Python 3.8 version of py-pyflakes the one that is run when
 you execute the commands without a version suffix (none selected so far),
 e.g. 'pyflakes', run:

     port select --set pyflakes py38-pyflakes
 }}}
