310This doc mirrors the `--help` for the 3 shell tools in the build sytsem:
311
3121. `configure` - Detect system features
3131. `_build/oils.sh` - Compile `oils-for-unix` source into an executable
3141. `install` - Install the executable, and symlinks to it
315
316<div id="toc">
317</div>
318
319## Note: Usage is Different Than Autotools
320
321To minimize build deps, all 3 of these tools are hand-written POSIX shell
322scripts. So this build system does **not** use GNU autotools, and it does not
323use `make`.
324
325Keep these differences in mind:
326
327- Settings are configured with **either** flags or env vars, as described
328 below.
329 - For example, use `./configure --cxx-for-configure mycc`, not `CXX=mycc
330 configure`.
331- If you pass `./configure --cxx-for-configure mycc`, you should also pass
332 `_build/oils.sh --cxx mycc`. The flag value is not remembered.
