#Prog:bamg2geo
#NAME: bamg2geo - convert bamg mesh in geo format
#@cindex mesh
#@pindex bamg2geo
#@pindex geo
#@fiindex @file{.bamg} bamg mesh
#@fiindex @file{.dmn} domain names
#@fiindex @file{.geo} mesh
#@toindex @code{bamg}
#SYNOPSIS:
#@example
#  bamg2geo @var{options} @var{input}[.bamg] @var{input}[.dmn]
#  bamg2geo @var{options} @var{input}[.bamg] -Cl @var{domlabel}
#  bamg2geo @var{options} @var{input}[.bamg] @{-dom @var{domname}@}*
#@end example
#
#DESCRIPTION:
#Convert a bamg @file{.bamg} into @file{.geo} one.
#The output goes to standart output.
#The @file{.dmn} file specifies the domain names,
#since @code{bamg} mesh generator uses numbers as domain labels.
#
#EXAMPLE:
#@example
#  bamg -g toto.bamgcad -o toto.bamg
#  bamg2geo toto.bamg toto.dmn > toto.geo
#@end example
#
#BAMG CAD FILE:
#This file describe the boundary of the mesh geometry.
#A basic example writes (See bamg documentation for more);
#@example
#  MeshVersionFormatted
#    0
#  Dimension
#    2
#  Vertices
#    4
#    0  0     1
#    1  0     2
#    1  1     3
#    0  1     4
#  Edges
#    4
#    1  2     101
#    2  3     102
#    3  4     103
#    4  1     104
#  hVertices
#    0.1 0.1 0.1 0.1
#@end example
#DOMAIN NAME FILE:
#This auxilliary @file{.dmn} file defines the boundary domain names
#as used by Rheolef, since @code{bamg} uses numeric
#labels for domains.
#@example
#  EdgeDomainNames
#    4
#    bottom
#    right
#    top
#    left
#@end example
#The domain name file can also specify additional vertices domain:
#@example
#  EdgeDomainNames
#    4
#    bottom
#    right
#    top
#    left
#  VerticeDomainNames
#    4
#    left_bottom
#    right_bottom
#    right_top
#    left_top
#@end example
#Vertice domain names are usefull for some special boundary conditions.
#OPTIONS:
#@table @code
#  @itemx -upgrade
#  @itemx -noupgrade
#	Default is to output a version 2 @file{.geo} file format. @xref{geo command}.	
#	With the @code{-noupgrade}, a version 1 file format is assumed.
#  @itemx -dom @var{dom1} ... -dom @var{domN}
#  @itemx -Cl @{poi|sed|sec|tro|con|NONE@}
#	Predefined domain name convention. See next section. 
#@end table
