# \brief Build binary archives from source

define HELP_MESSAGE
Build binary archives from source archives stored in the depot
usage:
$(firstword $(MAKEFILE_LIST)) <archive-path>...
The <archive-path> argument denotes the archive to create in the
form of a path. The first path element correponds to the identity
of the archive creator, the second element corresponds to the type
of the archive (bin or pkg), the third element specifies the target
architectures (e.g., x86_64), and the fourth element is the name
of the corresponding source archive including the version.
E.g., the user 'alan' may build the following archives:
alan/bin/x86_64/zlib/<version> - a binary archive of the zlib
library with the specified
version, built for the 64-bit
x86 architecture
alan/pkg/x86_32/wm/<version> - all binary archives needed by
the 'wm' package archive, built
for the 32-bit x86 architecture
The following arguments tweak the operation of the tool:
REBUILD=1 Replace existing archives with freshly created
ones.
VERBOSE= Show individual operations.
-j<N> Enable the parallel creation of packages where
<N> denotes the level of parallelism.
KEEP_BUILD_DIR=1 Do not remove build directories of built binary
packages. This is useful for debugging build
problems.
