WCSTOOLS This IRAF package uses the C language WCSTools library programs as external tasks. The source code is in the Src directory. Type "mkpkg " to set the binary directory to use. Type " mkpkg update" to produce binary executables in wcstools$bin. (with a default of bin.generic if "mkpkg is not used. Someday there should be CL wrappers to these tasks so IRAF parameter files can be used, but not yet. For now, type "help wcstools" to get one-line descriptions of the various WCSTools tasks and invoke the task name on the command line with no arguments to get a list of arguments for that task.
