Well try this code out under Euphoria:
control.e: global integer why=0
include.e: include control.e
if why=0 then standalone
elsif why=1 then included once
elsif why=2 then included twice
...
accounts.exw: include control.e why+=1 include include.e
graphics.exw: include control.e why+=1 include include.e
I use a namespace parser which bypasses Euphoria's use of include files.
hence this is untested for plain Eu (I only do clever inclusion tricks
with
my parser - RDS's vision of namespaces and such disagree with mine, and I
find my version is more flexible.)
So this trick works for me (but I rarely use it) but it may not work for
you.
