[Scons-users] using scons for workflow

[Keith Brown]

thanks for the response.

i suppose I am looking for a dependency example.

outputdir="/tmp/data"

1) run a shell script A
2) run a shell script B with Shell script A's output
3) run a R script with output of script B

Would like to see how the experts will do it.
