SDL supports that sort of thing (except for the embedded comment,
which I agree would be kinda nice):
http://sdl.ikayzo.org/display/SDL/Language+Guide
See section "String Literals"
Your example would look like this :
# This is a comment
value1 "This is a very long value \
split across multiple \
lines."
value2 "A short value"
module1 {
# These values are in a nested scope, so they are
# distinct from the settings above.
value1 "This is another long \
value split across \
multiple lines."
}
If you want the indentation *kept*, then use backquote strings (and
omit the line continuation backslashes).
The embedded comments could be easily added, but that would take it
into "non-standard behavior" territory. (I actually had to
deliberately disallow it just to match the behavior of the reference
implementation).
