- python_module build style now builds modules for python2/3 by default
- new python2_module and python3_module build styles for building
python2-only and python3-only packages respectively
- no more python_versions
- no need to define pycompile_version for Python modules anymore
(still needed for non-Python modules though)
- Python version and paths are now guessed automatically and a set of
useful variables can now be used in templates
- #!/usr/bin/python2 and #!/usr/bin/python3 are now the default shebangs
- /usr/bin/foo2 and /usr/bin/foo3 are now the default names for bin
scripts (for use with alternatives)
When set -o ERR is set the exit case wasn't executed. From the bash
manual page:
"The ERR trap is not executed if the
failed command is part of the command list immediately following
a while or until keyword, part of the test in an if statement,
part of a command executed in a && or || list except the command
following the final && or ||, any command in a pipeline but the
last, or if the command's return value is being inverted using
!. These are the same conditions obeyed by the errexit (-e)
option."
