illegal2vrml read the file protofile.wrl
which should contain such EXTERNPROTOs. The names of the EXTERNPROTOs should
start with the same prefix. The prefix is needed to deal with additional
illegal field names in valid VRML97 nodes.
In the next step illegal2vrml read the file file.wrl and replace all node
names which are identical to the EXTERNPROTOs without the prefix with the
names of the EXTERNPROTOs (with the prefix).
In the last step, the result is written to standard output.
set the name of the prefix of the EXTERNPROTOs. If this option is not used, the prefix is calculated from the proto names in protofile.wrl
Imagine a VRML97 file with a illegal extension to the WorldInfo node
