| void WriteCharDescription | ( | const FEATURE_DEFS_STRUCT & | FeatureDefs, |

Write a textual representation of CharDesc to File. The format used is to write out the number of feature sets which will be written followed by a representation of each feature set.
Each set starts with the short name for that feature followed by a description of the feature set. Feature sets which are not present are not written.
