[erlang-questions] passing an include path to escript

[Jayson Vantuyl]

According to the docs (and my tests), escript will only use - 
include_lib, not a regular -include.

The way to make that work is if you have the file in the code_path  
(hence, why it works for installed modules).  Since any modifications  
within the script happen after the -include_lib would be processed,  
you'll have to have the escript program set this path itself.

I can't find a way to do this.

I tried just giving it the flag that "erl" would take, didn't work.
I tried adding the flag via an environmental variable, also didn't  
work. (ERL_AFLAGS="-pa mypath")

When I use etap, I have my actual tests in a compiled module, so I  
don't have this problem.  That said, I don't know of any way to make  
this work.

I think the best way would be to add "-patha(...)" and "-pathz" to  
escript.

Anybody know how to get escript to modify its path?

Also, can anyone explain why -include() isn't allowed?
