Great article! I appreciate the coverage of the more esoteric and useful aspects of Vim. A couple of questions.
1. If I want to load the sql.vim syntax file in the standard syntax directory ($VIMFILES/syntax), what format should the syn include line take? I tried looking this up in the online help, but find the Vim ex syntax to be quite cryptic.
2. Can you (or someone) give some more details about generating tags. You talked about how to use them but I cannot seem to generate them. Right now I think Vim uses a different program to generate the tags than the pltags.pl file you mentioned.
