• Several files have no new line at the end.
• Do you plan to use btcr and tcr like this ../../scripts/{tcr|btcr} when you are in a specific scaffold?
• I prefer using a folder called bin instead of scripts 😜
• I'll add the build and test script for PHP. Do you prefer a new commit in this branch or a new branch?
