a couple tangle questions (tangle a single block, comment syntax)

Hello,

I'm moving my configuration files to an org file to be tangled, and I
have a couple questions.

First, is there a command to tangle a single block, or blocks in a
subtree?

Second, I like to have the :comments link option in my tangled files (to
reference where they were tangled from), but some files do not have an
emacs mode, so I use a "config" source block. For these files, org does
not know the syntax of comments, so it asks me for it. Can I specify the
syntax for comments in the header of the source block?

Thanks a lot,

Alan

Do you mean interactively?  With org-babel-tangle you can:

With one universal prefix argument, only tangle the block at point.

When two universal prefix arguments, only tangle blocks for the
tangle file of the block at point.

Thank you! I looked at the manual but forgot to look at the function's
documentation.

Now I just need to find a way to specify the syntax for comments in the
headers, and I'm all set.

I'm feeling silly. What I need to use is the "conf" language, not
"config". Sorry for the noise.
