# We use temporary variables to make the code more readable. Note, however,
# that we have to use macro arguments like `$(1)' directly in recipes since
# they are executed after variable expansion has happened: At that time
# those temporary variables normally have different values (from later calls
# to `FontFamily').
#
# The body (i.e., the third argument) of the `foreach' function that creates
# multiple targets must be encapsulated in separate multi-line variables;
# otherwise you get syntax warnings related to newline issues.
#
# To be able to create make targets at all, we have to use the `eval'
# function; this further implies to use `$$' instead `$' (except for macro
# arguments) in the called macros to avoid premature expansion. Note that
# within `$(if ...)' we even have to use `$$$$' for the recipe part.
