+ * tclUnixPort.h --
+ *
+ *	This header file handles porting issues that occur because of
+ *	differences between systems. It reads in UNIX-related header files and
+ *	sets up UNIX-related macros for Tcl's UNIX core. It should be the only
+ *	file that contains #ifdefs to handle different flavors of UNIX. This
+ *	file sets up the union of all UNIX-related things needed by any of the
+ *	Tcl core files. This file depends on configuration #defines such as
+ *	NO_DIRENT_H that are set up by the "configure" script.
+ *
+ *	Much of the material in this file was originally contributed by Karl
+ *	Lehenbauer, Mark Diekhans and Peter da Silva.
