[pdftex] creating a pdf file with specified named destinations

[Alessandro Bernardini]

How can I create a pdf file using tex so that I can specify named
destinations in the pdf file itself ?

For named destinations I mean that was is intended by Acrobat.

Is there a command like
/createnameddest{my-named-dest}
to create named destinations in a pdf file ?

So that i can link to that destination in the (end-) pdf file with:
myfile.pdf#my-named-dest         ?

And if I change the tex source and I recompile it,  the named destination
should be automatically rearranged too, so that
myfile.pdf#my-named-dest
always points to the correct content (like a given theorem....) in the file.
