// NOTES:
|
|
// >>> TBD: must deal with case where DSC file is in a CHM. I assume we must unpack it
|
|
// from CHM into a normal directory, then read it with BReadModel. Exception handling scheme
|
|
// must cope correctly with the fact that the error may be either from the CHM file or the
|
|
// DSC file. Maybe use CFileReader to read from the CHM file and write the copy
|
|
// to disk? JM 1/7/99
