+		      #defines used in Wish 2.0
+		      -------------------------
+
+$Revision: 41.1 $ $Date: 1995/12/29 02:57:38 $
+
+Here are the defines that are used in Wish 2.0. Code that uses specific
+library calls and system calls are appropriately ifdef'd.
+
+DEBUG				/* debugging code used in development */
+MALLOCDEBUG			/* malloc debugging code used in development */
+MINIX1_5			/* Minix 1.5 specific stuff */
+NOTYET				/* code that's not being used, & may never be */
+POSIXJOB			/* POSIX style job control */
+PROTO				/* Ansi-C function prototypes */
+STDARG				/* <stdarg.h> use */
+UCBJOB				/* 4.3BSD style job control */
+USES_DIRECT			/* struct direct instead of struct dirent */
+USES_GETWD			/* getwd() use instead of getcwd() */
+USES_MORESIG			/* sgtty moresig code */
+USES_SGTTY			/* bcopy() and sgttyb/TCIOGETP use */
+USES_TCGETA			/* termio/TCGETA use */
+USES_TERMIOS			/* termios/tcgetattr use */
+V7JOB				/* 7th Edition ptrace(1) job control */
+VARARGS				/* <varargs.h> use */
+
+A small amount of code is specific to some systems. The following systems
+are defined in the m_*.h files. Only the MINIX1_5 define is used in the
+source code. If you are porting Wish to another system, define a name for
+the system, but try not to use this when #ifdef'ing code. Use the #define's
+above, or create a new define, e.g #define USES_INDEX if using index().
+
+
+AUX2_01			/* A/UX 2.01 */
+COHERENT		/* Coherent */
+FREEBSD_1		/* FreeBSD 1.x */
+FREEBSD_2		/* FreeBSD 2.x */
+GENBSD			/* Generic BSD 4.x machine */
+GENSYSV			/* Generic SysV machine */
+J386BSD0_1		/* 386BSD-0.1 */
+MINIX1_5		/* Minix 1.5 */
+MINIX1_7		/* Minix 1.7 */
+OSX5_1_ATT		/* Pyramid under OSx 5.1a, SysV Universe */
+OSX5_1_BSD 		/* Pyramid OSx 5.1a, BSD Universe */
+SOLARIS_2		/* Solaris 2.x */
+SUNOS3			/* Sun OS 3.x */
+SUNOS4			/* Sun OS 4.x */
+ULTRIX4_2		/* Ultrix 4.2 */
+
+Job Control
+-----------
+
+	There are four styles of job control available: 7th Edition Unix
+job control (using ptrace), Berkeley job control, POSIX job control and
+no job control whatsoever. These are enabled by the following defines, only
+one of which should be defined.
+
+#define POSIXJOB	/* POSIX job control */
+#define V7JOB		/* 7th Edition Unix job control */
+#define UCBJOB		/* Berkeley job control */
+
+Argument Passing
+----------------
+
+	The prints() [and friends] functions take a variable number of
+arguments. Where possible, argument passing macros should be used. There
+are three main types: no argument passing macros, varargs.h style argument
+passing and stdarg.h stype argument passing macros. These are enabled by the
+following defines, only one of which should be defined.
+
+#define VARARGS		/* varargs.h style argument passing */
+#define STDARG		/* stdarg.h stype argument passing */
+
+
+Miscellaneous
+-------------
+
+	There are a few other miscellaneous defines which control things
+like types of functions used for directory searches, current working directory
+information.
+
+#define USES_GETWD	/* Uses getwd(), not getcwd() */
+
+#define PLONG int	/* The type of arguments to ptrace(). Minix 1.5 */
+			/* uses longs! This is only used when V7JOB is on */
+
+#define SIGTYPE void	/* Signal handlers return this type. Usually void or */
+			/* int, but might also be __sighandler_t */
+
+#define USES_DIRECT	/* Uses struct direct, not struct dirent */
+
+#define PROTO		/* The compiler supports Ansi-C prototyped function */
+			/* declarations */
+
+#define DEBUG		/* Debugging code in Wish is #ifdef'd with this. You */
+			/* should not need (or want) to turn this on. */

+
+1) Link the most appropriate file from the list of the m_*.h files to machine.h.
+   The current machine types are:
+
+	m_386bsd.h		386BSD-0.1
+	m_attpyr.h		OSx 5.1a, SysV Universe
+	m_aux.h			A/UX 2.01
+	m_bsdpyr.h		OSx 5.1a, BSD Universe
+	m_coherent.h		Coherent
+	m_freebsd1.h		FreeBSD 1.x
+	m_freebsd2.h		FreeBSD 2.x
+	m_freebsd4.h		FreeBSD 4.x
+	m_genbsd.h		Generic 4.x BSD machine
+	m_gensysv.h		Generic SysV machine
+	m_minix1.5.h		Minix 1.5
+	m_minix1.7.h		Minix 1.7
+	m_solaris.h		Solaris
+	m_sunos3.h		Sun OS 3.x
+	m_sunos4.h		Sun OS 4.x
+	m_ultrix.h		Ultrix 4.2
+
+   Not all of these have been tested recently, only those described in the
+   `Systems' file. If you get any to work, especially with the changes
+   required, let me know.
+
+   If there is no m_*.h file for your system, pick one which is close, and
+   alter it to work:
+
+	POSIX:		m_sunos4.h or m_386bsd.h
+	Old SYSV:	m_gensysv.h
+	4.3BSD:		m_genbsd.h
+
+   Put a unique system #define in the file, and try to #ifdef code with this
+   define only when absolutely necessary. The file `Ifdefs' has information
+   about what defines are available in Wish. Please send me a copy of the new
+   machine file when it works.
+
+2) Copy the file Std.Makefile to Makefile. Make sure Makefile is writeable.
+   Edit the Makefile to define how to compile the shell. You should define:
+
+	CFLAGS		The compiler flags used when compiling each .c file
+	LDFLAGS		The link flags used when linking the program
+	CC		The name of your compiler
+	DEFINES		Special defines needed during the compilation stage
+	CLIB		Any libraries needed during the link stage
+	FINAL_TOUCHES	Any final touches needed after the linking
+
+   Suggestions for these defines are given in the Makefile.
+
+3) Run `make' to make the shell.

+		Wish 2.0 - Warren's Interactive Shell
+		-------------------------------------
+
+Welcome to Wish, a sort-of-tcsh-like shell based largely on the Clam shell
+written by Callum Gibson. The aims of wish are:
+
+	+ to be as small as possible, so as to compile on small
+	  systems like Minix
+	+ to have some of the interactive features of tcsh, such
+	  as command-line editing, tab and ^D expansion, history,
+	  aliases etc.
+	+ to be portable across as many systems as possible,
+	+ to be fast and have minimal impact on the system.
+
+I worked on this shell from 1991 to 1996 and then gave up to finish off
+my Ph.D. This release of Wish is an alpha-release, and I doubt I will ever
+get back to finishing it off. It is known to run on FreeBSD 4.7, but I have
+not tried it on any other system since 1996.
+
+The manual is in nroff form in `Wish.1'. Instructions on how to compile wish
+are in the `Installation'. If you are porting wish to another system, read
+the file `Ifdefs', `Systems' and the `m_*.h' files.
+
+Anybody who would like to take over development of the shell should email me,
+as I can supply some good documentation about the development up to now, and
+also a good description of the shell's internals.
