| This directory used to contain scripted implementations of builtins | |
| that have since been rewritten in C. | |
| They have now been removed, but can be retrieved from an older commit | |
| that removed them from this directory. | |
| They're interesting for their reference value to any aspiring plumbing | |
| users who want to learn how pieces can be fit together, but in many | |
| cases have drifted enough from the actual implementations Git uses to | |
| be instructive. | |
| Other things that can be useful: | |
| * Some commands such as git-gc wrap other commands, and what they're | |
| doing behind the scenes can be seen by running them under | |
| GIT_TRACE=1 | |
| * Doing `git log` on paths matching '*--helper.c' will show | |
| incremental effort in the direction of moving existing shell | |
| scripts to C. |
