# composed by a bunch of applications and tools that can be built

# independently of each other, you can simply put them into various
|
|
# subdirectories, then have a top level GNUmakefile which has them as
|
|
# PARALLEL_SUBDIRECTORIES; they will be built in parallel, if possible
|
|
# (or in a random serial order if parallel building is not used).
|

# If you do require the subdirectories to be built in strict order,

# you can use serial-subdirectories.make which will build them in the

# specified order.
