I want to transform a pair of angular coordinates in datum WGS84 to NTF
Lambert 2. I have written this line :

./cs2cs +proj=latlong +datum=WGS84 +ellps=GRS80 +to +proj=lcc +lat_0=46.8000
+lat_1=46.8000 +lon_0=2.3372291 +k_0=0.99987742 +x_0=600000 +y_0=200000
+a=6378249.2 +b=6356515 +ellps=clrk80

The input coordinates are :

2d39'48882"E 48d32'8575"N

But the coordinates transformed come out wrong and i don't understand why :

1575621.19      743408.43 0.00

(the coordinates should turn around these values :

 600000 2400000

Does any one have the solution to this, or at least some in depth
documentation on how to use proj ?
