#Prog:grummp2geo
#NAME: grummp2geo - convert grummp mesh in geo format
#@cindex mesh
#@pindex grummp2geo
#@pindex geo
#@fiindex @file{.g} grummp mesh
#@fiindex @file{.dmn} domain names
#@fiindex @file{.geo} mesh
#@toindex grummp
#SYNOPSIS:
#@example
#  grummp @var{options} @var{input}[.g] [@var{input}[.dmn]]
#@end example
#
#DESCRIPTION:
#Convert a grummp @file{.g} into @file{.geo} one.
#The output goes to standart output.
#The @file{.dmn} file specifies the domain names,
#since @code{grummp} mesh generators use numbers as domain labels.
#
#EXAMPLE:
#@example
#  grummp2geo toto.g toto.dmn > toto.geo
#@end example
#End:
