tlbuild: Build in parallel
4.3 Build in parallel
=====================
The TL build system carefully formulates dependencies as well as 'make'
rules when a tool (such as 'tangle', 'ctangle', and 'convert') creates
several output files. This allows for parallel builds ('make -j N' with
N>1 or even 'make -j') that can considerably speed up the TL build.
Incidentally, a noticeable speed-up can be independently gained by
using a configure cache file, i.e., specifying the 'configure' option
'-C' (recommended).
