"""
|
|
Climb dependencies without using build groups and without annotating them.
|
|
|
|
In practice, one may want to avoid this:
|
|
* This adds some overhead as the task generators have to be searched and processed
|
|
* This is also unlikely to work in the real-world (complex targets, not all dependencies are file-based, etc)
|
|
* This also makes the dependencies more complicated to understand when reading a wscript file (what requires what?)
|
|
|
|
This example will create "d.txt" and all the required files but no "aa*.txt".
|
|
The target "john" is hard-coded below, just call "waf", or comment the line to call "waf --targets=john"
