[Proj] Trouble with a projection

[Spencer Cox]

Good afternoon,

Total newbie to proj... warning...danger...etc.

I am trying to use the following projection file in a MS4W mapfile.  To 
do so I have added it to the espg file in the proj libraries.  This 
seems to almost be working as below but I the reference latitute isn't 
included.  How would I modify that ESPG file entry to include a 
reference parallel.  Alternatively is there a resource would outlines 
all the variables you can use in such a file?  I don't even necessarily 
need to use the fake ESPG number in ESPG file combo.  Is there a 
resource that specifies all the parameters you can use to define a 
projection in a map file?

#<ESPG Entry>
<20851> +proj=lcc +lat_0=9.930000 +lon_0=-84.333333 +k_0=1 
+x_0=499784.42 +y_0=271970.62 +ellps=clrk66 +units=m +no_defs  no_defs <>
#</ESPG Entry>

Summarized:

*Lambert Norte*
Projection: Lambert Conic Conformal
Spheroid: Clarke 1866
Central Meridian: -84.33333...
Reference Latitude: 10.466666...
Standard Parallel1: 9.93
Standard Parallel2: 11
False Easting: 499784.42
False Northing: 271970.62


 From Esri File:

PROJCS["Cost Rica 
Norte",GEOGCS["GCS_Clarke_1866",DATUM["D_Clarke_1866",SPHEROID["Clarke_1866",6378206.4,294.9786982]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Lambert_Conformal_Conic"],PARAMETER["False_Easting",499784.42],PARAMETER["False_Northing",271970.62],PARAMETER["Central_Meridian",-84.33333333333333],PARAMETER["Standard_Parallel_1",9.93],PARAMETER["Standard_Parallel_2",11.0],PARAMETER["Scale_Factor",1.0],PARAMETER["Latitude_Of_Origin",10.46666666666667],UNIT["Meter",1.0]]

Thanks for your help.
