[GRASSLIST:145] s.label -- MIA?

[Matej Cepl]

Hi,

I am fairly new to GRASS (and GIS as such -- being lawyer and 
sociologist, I didn't need maps so far :-), so this may be silly 
question. I need to create EPS map from vector file (something similar 
to this map of Boston[1]). Manpage of ps.map tells me, that I need 
labels to display names of towns, but the ``user'' interface of p.label 
seems to me too dreadfull to even think about using it. I found 
a manpage for program s.label, which seems to be able to help me. In 
order to import vector area categories and their labels to sites, I have 
even created a Python script (see below; would you be so kind and 
comment on it, please? I am really newbie in GRASS and not the best 
programmer in the first place). However, when looking for the program 
itself, I found that it is not present neither in the binary tarball of 
grass 5.0.2 (April 2003) I have got yesterday from grass.ibiblio.org, 
nor in the Debian package of 5.0.0pre4 I used before.

Could anybody help me and locate a copy of it (probably the best would 
be a binary version for the above mentioned binary package, because I do 
not have sources and enough space on harddisk to compile whole GRASS, 
but if only sources are available, then I will do it)? Thanks.

   Have a nice day,

      Matej Cepl
