ob, opinionated build

ob builds C and C++ programs with Ninja if they are structured in its opinionated way:

• each source file is tracked in Git;
• each #include within the project is source-relative;
• each foo.c or foo.cc defines int main(...) or has a corresponding foo.h;
• each source file defining int main(...) with test in its name is a unit test.

To build in default mode:

ob

To build in debug, release, ASAN, or TSAN mode:

ob [-D|--debug] [-R|--release] [-A|--asan] [-T|--tsan]

Any other command line flags or arguments are passed to Ninja.

ob recognizes the following environment variables: CC, CXX, CPPFLAGS, CFLAGS, CXXFLAGS, LDFLAGS.
