Support the popular pip editable installation mode.
To work-around a problem in setuptools' develop target, generalize
'install_dir' to say all packages are in 'src' (for more info, see:
https://github.com/pypa/pip/issues/126).
Remove pre-generated bin/tito-dev script.
Create tito.cli.main() which serves as command line's entry point that
can be used:
- by setuptools' 'console_scripts' entry point mechanism for automatic
script creation,
- via 'if __name__ == "__main__":'.
Remove pre-generated bin/tito script.
Update SPEC file.
Tito passes "git archive" a tree ID. The "git archive" man page states:
git archive behaves differently when given a tree ID versus when
given a commit ID or tag ID. In the first case the current time
is used as the modification time of each file in the archive.
Using the current time means that every time we build the source
tarball, the file fingerprint will change since the metadata in the
tarball changes. We don't want that since build systems track the
fingerprint to see if the actual source has changed.
This process was previously handled in an enigmatic Perl script that
lacked any comments whatsoever. Converting it to well-commented Python
makes the process less mysterious and speedier since Tito doesn't need
to shell out to Perl.
Add bin/ to the end of your PATH and tito-dev will run everything from
source checkout rather than what may/may not be installed on the system.
This includes the perl script in bin/ which land in /usr/bin normally.
