redo-ifcreate1
Rebuild the current target if source files are created
Usage
redo-ifcreate [sources ...]
Overview
Normally redo-ifcreate is run from a .do file that has been executed by redo(1). See redo(1) for more details.
redo-ifcreate takes a list of nonexistent files (sources) and adds them as dependencies to the current target (the one calling redo-ifcreate). If any of those files are created in the future, the target will be marked as needing to be rebuilt.
If one of the given files exists at the time redo-ifcreate is called, it will return a nonzero exit code.
If you want to declare dependencies on files that already exist, use redo-ifchange(1) instead.
