Function: polrootsmod
Section: polynomials
C-Name: rootmod0
Prototype: GGD0,L,
Help: polrootsmod(x,p,{flag=0}): roots mod p of the polynomial x. flag is
 optional, and can be 0: default, or 1: use a naive search, useful for small
 p
Description: 
 (pol, int, ?0):vec	rootmod($1, $2)
 (pol, int, 1):vec	rootmod2($1, $2)
 (pol, int, #small):vec	$"Bad flag in polrootsmod"
 (pol, int, small):vec	rootmod0($1, $2, $3)
