"""
Travis builds are sometimes not reproducible when run using the build.sh script ("the build script") generated by
travis-build. Thus, to increase the number of reproducible builds, we modify the build script.
This function applies the necessary modifications to the build script located at `build_sh_path` and writes the
modified file to that same location.
This set of modifications was developed over time as we observed more build reproducibility issues that were likely
caused by using the build script generated by travis-build.
There's a file in Google Drive that explains the modifications applied to the build script.
A previous version of this function included several additional build script modifications that have since been
removed because travis-build was patched to generate build scripts that need fewer modifications. The BugSwarm
pipeline utilizes the patched version of travis-build to generate build scripts.
:param repo: A GitHub repository slug
:param build_sh_path: The path to the unmodified build script (generated by travis-build).
