  +lrs is split into many small crates and provides incremental compilation
   independent of the rustc compiler. Compiling a single crate during development
   often takes less than a second. To this end, lrs comes with its own
   build system--lrs_build, discussed below--which ensures that only the minimal
  
positive.code: 
  === Direct system calls
  
  lrs interact with the kernel directly through system calls. That is, lrs does
  not depend on a libc for 99% of the work. This allows us to use kernel features
  that do not (yet) have an equivalent libc function and removes an unnecessary
  layer of abstraction.
  
negative.code: This is because lrs comes with its own compiler driver that takes care of
  injecting lrs instead of rust.
