"""
|
|
Modification to handle folders as if they were files.
|
|
|
|
Usually, the target folders are created automatically (Node.find_or_declare)
|
|
for files that need them so this is not really necessary.
|
|
|
|
This modification incurs a performance penalty (computing hashes,
|
|
creating additional tasks, checking if the folders are there
|
|
vs just creating the folders if missing), and can conceal serious
|
|
errors (confusing files and folders for example).
|
|
|
|
The build order will not look at the parent folder relationships,
|
|
we will need a testcase for this (overriding the function
|
|
Task.set_file_constraints is trivial)
