 The text and source files in this repository originally used CR line endings, as usual for Apple II text files, but they have been converted to use LF line endings because that is the format expected by Git. If you wish to move them to a real or emulated Apple II and build them there, you will need to convert them back to CR line endings.

 Alternatively, you can keep the LF line endings in your working copy of the Git repository, but convert them when you copy the files to an Apple II. There are various tools to do this.  One option is `udl`, which is [available][udl] both as a IIGS shell utility and as C code that can be built and used on modern systems.

+In addition to converting the line endings, you will also have to set the files to the appropriate file types before building ORCA/C on a IIGS. The included `settypes` script (for use under the ORCA shell) does this for the sources to the ORCA/C compiler itself, although it does not currently cover the test cases and headers.
