In cases where a compile did not proceed to completion (e.g. you intentionally exited early or an exception was raised) a temporary directory may still exist in the root of the repository on the path `master_ttf`. This can be removed with:
```
$ rm -rf master_ttf
```
### Uninstall Details
fontmake and fonttools are Python packages and are uninstalled with pip.
The FreeType library (including its build dependency Harfbuzz), ttfautohint, sfnt2woff-zopfli, and woff2 are built in directories on your $HOME path. They are not installed on your $PATH (unless of course you have defined $HOME on $PATH) so they **will not** work from the command line with the name of the executable file only (e.g. `$ ttfautohint [file path]`). This is intentional.
Repeat execution of the build process cleans up the temporary directory `master_ttf` if found so this step is not mandatory to repeat a build and should not lead to errors with the build.
