+ A new option <c>{n2n,TypeName}</c> can be used to
+ enable generation of conversion functions from name to number
+ and vice versa for selected ENUMERATION types.
+ The option can be repeated many times in order to specify several
+ types in the same file.<br/>
+ If the <c>TypeName</c> specified does not exists or is not an
+ ENUMERATION type, the compilation will be terminated with an
+ error code.<br/>
+ Below follows an example on how to use the option from the command line with <c>erlc</c>:<br/>
+ <c>erlc -bper_bin +optimize +driver +"{n2n,'CauseMisc'}" +"{n2n,'CausePcl'}" MyModyle.asn</c>
