Original readme follows: dtdesc - The DataType Descriptor Tools Here you have two tools to create and disassemble DataType descriptors. DataType descriptors are those little files in Devs:DataTypes/ , which are used by the DataType system to recognice the type of a file. DataType descriptors are IFF-FORMs of type DTYP. They contain different chunks. The most important are: NAME : Name of the DataType, in most cases identical to the filename FVER : Amiga-version-string (optional) DTHD : DataTypeHeader The most important chunk. Contains a struct DataTypeHeader as descriped in <datatypes/datatypes.h> and the strings for this struct. DTCD : Code-chunk This chunk contains executable code. So you can have a function to decide the type of a file. Because this is not portable to AROS, it is not supported by dtdesc. For more informations see the header <datatypes/datatypes.h> . examinedtdesc is used to disassemble an existing DataType descriptor. It accepts as its only argument the filename of a DataType descriptor. It outputs a DataType description suitable for createdtdesc (see below) to stdout. This DataType description is an ASCII-file, for details see the file FORMAT . createdtdesc is a tool to create a DataType descriptor. It has one required argument: the filename of a DataType description (*.dtd file). Optional with the "-o" switch you can define the Name of the output DataType descriptor. When no output-name is given, the name for the Datatype descriptor is taken from the "Name" keyword from the Datatype description. The resulting Datatype descriptor is placed in the current directory. Yes I know my naming convention is a bit confusing, come with better names! |
