Hello all,

1) Is it possible to change content of application resource file - (.app 
file) on the fly?
I changed some environment parameters using application:set_env, and it has 
but content in .app file still the same. Is it normal?

2) Additionally, I noticed, that whole resource file was built in the .boot 
file, and target system  uses environment parameters this boot, not .app 
Should I use sys.config instead?

Thx in adv,

Sorry if it is FAQ
