jWrap history
---------------
jWrap was designed in 1998 mainly to test VxWorks/Tornado programs, and then was forgotten for 20 years.
I restore for modern Linux/64 bits because I wanted a foundation for Automotive Grade Linux Json Bindings.
As today I only check the C backend. WHile most backend are obsolete (VxWorks, Tcl, Java, ...). jWrap remains
a very good foundation for who ever need to parse C/C++ and generate automatically stub to encode/decode
object from one model to an other one, example: json<->C


jWrap/jTcl/zDemo for examples
------------------------------------
Example: C code
```
PUBLIC int fact(int n) {
  if (n <= 1) return 1;
  else return n*fact(n-1);
}
PUBLIC int mod(int n, int m) {
  return (n % m);
}
PUBLIC char *get_time() {
    long            ltime;
    time(&ltime);
    // don't forget to return a valid malloced string
    const char*now = ctime(&ltime);
    char *dup= strdup(now);
    return dup;
}
```

Simple Test program
```
puts [DemoSimple.get_time]
set tcl_precision 17
puts "My Double = $JWRAP(MyDouble)"
for {set i 0} {$i < 14} {incr i 1} {
    set n [DemoSimple.fact $i];
    puts "$i factorial is $n"
}
for {set i 1} {$i < 250} {incr i 1} {
    for {set j 1} {$j < 250} {incr j 1} {
	set n [DemoSimple.mod $i $j]
	set JWRAP(MyDouble) [expr {$JWRAP(MyDouble) + $n}]
    }
}
puts "MyDouble = $JWRAP(MyDouble)"
puts "---------------------------"
puts [DemoSimple.get_time]
```
