This is simple utility which will add binary file to the TRDOS image TRD.

Intended use is for assembling of TRD images from not always empty
template and many binary files which can be automatically added on disk.
For example if you want add one or more CODE files to the template with
prepared boot.B and/or program loader BASIC program or if you want add
CODE to any TRD image in general.

bin2trd doesn't do any other modifications to the TRD image, all files,
even deleted files, will be preserved.

This utility will create only CODE on target image. Cannot create other
file types supported by TRDOS.
