Implement in module
Given test.in containing something along these lines:
foo = $foo$
Now we can do:
using in
file{test}: in{test.in}
file{test}: foo = FOO
The alternative variable substitution symbol can be specified with the
in.symbol variable and lax (instead of the default strict) mode with
in.substitution. For example:
file{test}: in.symbol = '@'
file{test}: in.substitution = lax
