-\fIM4\fR is a macro processor intended as a front end
-for Ratfor, Pascal, and other languages that do not have a built-in macro 
-processing capability.  M4 reads standard input, the processed text is 
-written on the standard output.
-.PP
-The options and their effects are as follows:
-
-.in +0.5i
-.ta 1.25i
-\(enD name[=val]	Defines name to val, or to null in val's absence.
-.br
-\(enU name	Undefines name.
-.in -0.5i
-
-.PP
-Macro calls have the form: name(arg1,arg2, ..., argn)
-
-The \*(OQ(\*(CQ must immediately follow the name of the macro.  
-If the name of a 
-defined macro is not followed by a ( it is taken to be a call of that macro 
-with no arguments, i.e. name().  Potential macro names consist of alphabetic 
-letters and digits.
-.PP
-Leading unquoted blanks, tabs and newlines are ignored while collecting 
-arguments.  Left and right single quotes are used to quote strings.  The value 
-of a quoted string is the string stripped of the quotes.
-.PP
-When a macro name is recognized, its arguments are collected by searching 
-for a matching ).  If fewer arguments are supplied than are in the macro 
-definition, the trailing arguments are taken to be null.  Macro evaluation 
-proceeds normally during the collection of the arguments, and any commas or 
-right parentheses which happen to turn up within the value of a nested call 
-are as effective as those in the original input text.  (This is typically 
-referred as  inside-out macro expansion.)  After argument collection, the 
-value of the macro is pushed back onto the input stream and rescanned.  
-.PP
-M4 makes available the following built-in macros.  They may be 
-redefined, but once this is done the original meaning is lost.  Their values 
-are null unless otherwise stated.
-.PP
-\fBdefine "(name [, val])"\fR the second argument is installed as the value of 
-the macro whose name is the first argument.  If there is no second argument, 
-the value is null.  Each occurrence of $ n in the replacement text, where n is 
-a digit, is replaced by the n -th argument.  Argument 0 is the name of the 
-macro; missing arguments are replaced by the null string.
-.PP
-\fBdefn "(name [, name ...])"\fR returns the quoted definition of its 
-argument(s). Useful in renaming macros.
-.PP
-\fBundefine "(name [, name ...])"\fR removes the definition of the macro(s) 
-named. If there is more than one definition for the named macro, (due to 
-previous use of pushdef) all definitions are removed.
-.PP
-\fBpushdef "(name [, val])"\fR like define, but saves any previous definition 
-by stacking the current definition.
-.PP
-\fBpopdef "(name [, name ...])"\fR removes current definition of its 
-argument(s), exposing the previous one if any.
-.PP
-\fBifdef "(name, if-def [, ifnot-def])"\fR if the first argument is defined, 
-the value is the second argument, otherwise the third.  If there is no third 
-argument, the value is null.  A word indicating the current operating system 
-is predefined.  (e.g. unix or vms).
-.PP
-\fBshift "(arg, arg, arg, ...)"\fR returns all but its first argument.  The 
-other arguments are quoted and pushed back with commas in between.  The 
-quoting nullifies the effect of the extra scan that will subsequently be 
-performed.
-.PP
-\fBchangequote "(lqchar, rqchar)"\fR change quote symbols to the first and 
-second arguments.  With no arguments, the quotes are reset back to the default 
-characters. (i.e., `').
-.PP
-\fBchangecom "(lcchar, rcchar)"\fR change left and right comment markers from 
-the default # and newline.  With no arguments, the comment mechanism is reset 
-back to the default characters.  With one argument, the left marker becomes 
-the argument and the right marker becomes newline.  With two arguments, both 
-markers are affected.
-.PP
-\fBdivert "(divnum)"\fR maintains 10 output streams, numbered 0-9.  Initially 
-stream 0 is the current stream. The divert macro changes the current output 
-stream to its (digit-string) argument.  Output diverted to a stream other than 
-0 through 9 is lost.
-.PP
-\fBundivert "([divnum [, divnum ...]])"\fR causes immediate output of text from 
-diversions named as argument(s), or all diversions if no argument.  Text may 
-be undiverted into another diversion.  Undiverting discards the diverted text. 
-At the end of input processing, M4 forces an automatic undivert unless is 
-defined.
-.PP
-\fBdivnum "()"\fR returns the value of the current output stream.
-.PP
-\fBdnl "()"\fR reads and discards characters up to and including the next 
-newline.
-.PP
-\fBifelse "(arg, arg, if-same [, ifnot-same | arg, arg ...])"\fR has three or 
-more arguments.  If the first argument is the same string as the second, then 
-the value is the third argument.  If not, and if there are more than four 
-arguments, the process is repeated with arguments 4, 5, 6 and 7.  Otherwise, 
-the value is either the fourth string, or, if it is not present, null.
-.PP
-\fBincr "(num)"\fR returns the value of its argument incremented by 1.  The 
-value of the argument is calculated by interpreting an initial digit-string as 
-a decimal number.
-.PP
-\fBdecr "(num)"\fR returns the value of its argument decremented by 1.
-.PP
-\fBeval "(expression)"\fR evaluates its argument as a constant expression, 
-using integer arithmetic.  The evaluation mechanism is very similar to that of 
-cpp (#if expression).  The expression can involve only integer constants and 
-character constants, possibly connected by the binary operators
-.HS
-.in +0.5i
-*    /    %    +    -    >>   <<    <    >   <=   >=   ==   !=   &    ^    |     &&   ||
-.in -0.5i
-.HS
-or the unary operators - ! or tilde or by the ternary operator ? : .  
-Parentheses may be used for grouping. Octal numbers may be specified as in C.
-.PP
-\fBlen "(string)"\fR returns the number of characters in its argument.
-.PP
-\fBindex "(search-string, string)"\fR returns the position in its first 
-argument where the second argument begins (zero origin), or 1 if the second 
-argument does not occur.
-.PP
-\fBsubstr "(string, index [, length])"\fR returns a substring of its first 
-argument. The second argument is a zero origin number selecting the first 
-character (internally treated as an expression); the third argument indicates 
-the length of the substring.  A missing third argument is taken to be large 
-enough to extend to the end of the first string. 
-.PP
-\fBtranslit  "(source, from [, to])"\fR transliterates the characters in its 
-first argument from the set given by the second argument to the set given by 
-the third.  If the third argument is shorter than the second, all extra 
-characters in the second argument are deleted from the first argument. If the 
-third argument is missing altogether, all characters in the second argument 
-are deleted from the first argument.
-.PP
-\fBinclude "(filename)"\fR returns the contents of the file that is 
-named in the argument.
-.PP
-\fBsinclude "(filename)"\fRis identical to include, except that it says nothing 
-if the file is inaccessable.
-.PP
-\fBpaste "(filename)"\fR returns the contents of the file named in the argument
-without any processing, unlike include.
-.PP
-\fBspaste "(filename)"\fR is identical to paste, except that it says nothing if
-the file is inaccessibl[De.
-.PP
-\fBsyscmd "(command)"\fR executes the 
-.Ux
-command given in the first argument.  
-No value is returned.
-.PP
-\fBsysval "()"\fR is the return code from the last call to syscmd.
- .PP
-\fBmaketemp \*(OQ(string)"\fR fills in a string of XXXXXX in its argument with the 
-current process ID.
-.PP
-\fBm4exit "([exitcode])"\fR causes immediate exit from M4.  Argument 1, if 
-given, is the exit code; the default is 0.
-.PP
-\fBm4wrap "(m4-macro-or-built-n)"\fR argument 1 will be pushed back at final 
-EOF; example: m4wrap(`dumptable()').
-.PP
-\fBerrprint "(str [, str, str, ...])"\fR prints its argument(s) on stderr. If 
-there is more than one argument, each argument is separated by a space during 
-the output.  An arbitrary number of arguments may be supplied.
-.PP
-\fBdumpdef "([name, name, ...])"\fR prints current names and definitions, for 
-the named items, or for all if no arguments are given.
