special heading

[Idris S Hamid <ishamid@attbi.com>]

Dear gang,

I'm having trouble with a special heading. I have written a treatise where 
everything is numbered in sections, subsections, etc.  I need an introductory 
section-like command, say,

\definehead [introduction][section]

where 
1. "Introduction" is marked in the table of contents without a number, and
2.  absolutely nothing is marked in the main text;
3. the first section is still marked as `1' in the main text and the TOC. 

Another possibility I'm considering:

1. "Introduction" is marked in the table of contents without a number, and
2. "Introduction" is marked centered in the main text without a number;
3. the first section is still marked as `1' in the main text and the TOC. 

Thnx in advance
Idris
