* `build` is an alias which on first use invokes `build-dir --build` to select a build directory, reconfigure the `build` alias, and invoke the `build` alias on the selected build directory. * `debug` is an alias to the installed system native debugger. * `build-dir` is a function to select a build directory by reconfiguring the `build` alias, it detects `build.ninja` or `Makefile` in the build directory and selects the appropriate `ninja` or `make` command. Depends on the `build-dir.py` Python script which uses the `pick` package to interactively select the build directory. * `build-run` is a function which builds the specified target then attempts to run it, making the assumption it resides in the `bin` subdirectory of the build directory. * `build-debug` is a function which build the specified tared then attempts to debug it using the system native debugger, making the assumption it resides in the `bin` subdirectory of the build directory.
