0007 GDML read/write
0008 ---------------
0009
0010 This example demonstrates the usage of the GDML reader and writer. It allows
0011 to export geometry descriptions in an application independent format (GDML,
0012 Geometry Description Markup Language).
0013 The GDML files can be then used to interchange geometries between different
0014 applications and users.
0015
0016 The detector construction consists of a call to GDMLProcessor which parses a
0017 GDML file and returns the pointer to the world volume. The user can also write
0018 her/his own GDML file and use it as the primary input format for her/his Geant4
0019 application.
0020
0021 Several simple GDML files are provided:
0022 - axes.gdml, showing loading and orientation of Cartesian axes;
0023 - solids.gdml, list of all supported solids with placement;
0024 - scale.gdml, a simple diamond structure made of extruded solids;
0025 - divisionvol.gdml, a divided box;
0026 - parameterized.gdml, a parameterised box;
0027 - pTube.gdml, a parameterised tube;
0028 - auxiliary.gdml, showing association of volume with auxiliary information;
0029 - etc...

0031 HOW TO BUILD THE EXAMPLE ?
0032
0033 - You need to have built the persistency/gdml module by having
0034 set the -DGEANT4_USE_GDML=ON flag during the CMAKE configuration step,
0035 as well as the -DXERCESC_ROOT_DIR=<path_to_xercesc> flag pointing to
0036 the path where the XercesC XML parser package is installed in your system.
0037
0038 - Compile and link to generate the executable (in your CMAKE build directory):
0039 % make
0040
0041 - Execute the application.
0042 o For reading and visualize interactively a GDML file:
0043 % load_gdml [GDML-file-in].gdml
0044
0045 o For reading, writing and visualize interactively a GDML file:
0046 % load_gdml [GDML-file-in].gdml [GDML-file-out].gdml
0047
0048 o For reading, writing a GDML file and running in batch a macro:
0049 % load_gdml [GDML-file-in].gdml [GDML-file-out].gdml [macro].in
