Proj.4 definition for USA_Contiguous_Lambert_Conformal_Conic

[Randy How]

I'm trying to support a specific projection in MapServer:
USA_Contiguous_Lambert_Conformal_Conic
 
1) Why it wouldn't be in proj/nad/epsg in the first place, I'm sure there's
a good reason.

2) Now that it's added to proj/nad/epsg file, it produces a map.  But the
scale is calculated incorrectly.  The datasets at larger scales are not
displaying.  What other info does mapserver need to calculate the scale
correctly?
