Released runj v0.1 and runj v0.2, run a UNIX command in sub-processes with line-buffered I/O.

Yesterday I released runj v0.1 and today I released runj v0.2 with a couple of important fixes.

runj is a UNIX command to run a command in an arbitrary number N of sub-processes with line-buffered input and output.

See the project page :

• runj on Github
• runj on KmxGit

Our in-house use case for runj is for KC3 :

• KC3 ships runj in a submodule for ease of use. Just running make in runj should work everywhere. No configure needed so our own scripts always call make -C runj before calling runj.
• update_sources now uses runj for going through subdirectories
• configure now uses runj for goind through subdirectories
• all test suites running in a subdirectory full of .kc3 files are now unified under a modular test framework that calls runj to run all test targets in parallel. Example :

for TARGET in $TARGETS; do
    echo "( ../test_runner ${TEST_RUNNER} ${TARGET}; )"
done | ../../bin/runj -1 /bin/sh
