I have some proposed modifications to RweaveLatex.Rd which I include
here as a patch against the R-devel version of the file from svn. I
have added comments about the issue that Liviu raised, the use of
the [nogin] option and while I was at it, the [noae] option as well.
There are added to the 'details' section of the file.
OK, once more....
I noted a typo and also neglected to add pointers to the Details
section in the descriptions of the height and width options.
Here is a corrected version of the patch file.
