<graph>
digraph G{
rankdir=LR
ResultFile [fontsize=8 shape=box3d]
MainFile->ResultFile;
edge [style=dashed label="included in" fontsize=8]
Generated1->MainFile
Generated2->MainFile
Generated3->MainFile
Generated4->MainFile

edge [color=blue style=solid label=generated]
Generator->Generated1
Generator->Generated2
Generator->Generated3
Generator->Generated4
}
</graph>

Consider the following situation.

* <tt>MainFile</tt> includes some <tt>GeneratedNN</tt> files (count of these files is unknown)
* All these <tt>GeneratedNN</tt> files generated by one <tt>Generator</tt> file (for example, python script).
* All these <tt>GeneratedNN</tt> files needed to be rescanned after generation (they can include other files).

I scan <tt>MainFile</tt>, and then I see inclusion of <tt>Generated1</tt> file,
I add something like this:
cmd=env.Command(Generated1, Generator, RunMePlease)

But actually I need
cmd=env.Command([Generated1,Generated2,…,GeneratedN], Generator, RunMePlease)
but I must add targets incrementally during <tt>MainFile</tt> scan…

{{question}} So the question is: How to dynamically add targets to Command?
I try something like
Generator.executor.targets.append(env.fs.Entry(GeneratedN))
but it seems not working…
