The whole point is that this feature would be available in any program.
Think as an end-user, and consider the following cases:
1. One of the program you use allow to set the sample rate with the "-r
rate" syntax, another with the "-ar rate" syntax, another with "--ar=rate",
another either with "-R rate" or with "-O ar=rate", and two of them do not
allow to set the sample rate at all.
2. Same as the above, but you can also write "[ar=rate]filename" instead of
just "filename", and it always work exactly the same for all programs.
(Again, the syntax is only an example; I like this one though.)
Which one do you prefer?
As for myself, I choose 2 without hesitation, even if it means a few hundred
more line of code in a library.
