[GRASSLIST:200] Several newbie sites questions

[Antonios Christofides]

I'm sorry to keep asking silly questions, but the documentation is
lacking; so are the archives.

Suppose I have a map with sites representing residential areas, in two
categories: 1 - villages, 2 - towns.

1) How do I associate each site with a name (that is, specify the
   name of each village and town)?

2) How do I tell ps.map to draw category 1 sites with a different
   icon from that of category 2? I think I need something like line_cat,
   but for sites.

Thanks!
