Is it possible to change .Xresources interactively?

Question

What I have in mind is something like:

#include $PATH_TO_FILE

in .Xresources, so that I could change the value of PATH_TO_FILE and run xrdb -merge

Answer 1

Apparently, it can't. What one can do is #include /path/to/symlink and then use PATH_TO_FILE in a script to change the file that symlink points to.
