;;; The packages that scsh uses/defines.

|
;;; Note: field-reader package (fr.scm) and here docs use READ-LINE.
|
|
;;; It is defined in rdelim.scm.
|
|
|
|
;;; You link up a scsh package by defining a package named OS-DEPENDENT
|
|
;;; that satisfies the interfaces for packages
|
|
;;; buffered-io-flags
|
|
;;; posix-fdflags
|
|
;;; posix-errno
|
|
;;; posix-signals
|
|
;;; Anything else it provides should be specified in an interface called
|
|
;;; os-extras-interface. See the scsh structure below.
|
|
;;; Then the scsh structure can be instantiated.
|
|
;;;
|
|
;;; The architecture directories, like next/ and irix/ and so forth,
|
|
;;; provide packages that can serve as the os-dependent package. E.g.,
|
|
;;; the next-defs package, defined in next/packages.
|
|
;;;
|
|
;;; This whole mechanism would be better solved with a functor.

;;; The LET-OPT package for optional argument parsing & defaulting
|
|
;;; is found in the let-opt.scm file.
