       checkbrack -- check parenthesis and bracket count

       checkbrack [-p] file...

       Displays	 each  line  of	 the file(s), together with their open bracket
       count that is reached at	the end	of line. Particularly, it  allows  you
       to  find	 missing  closing brackets. This is especially helpful because
       the Perl	interpreter for	example	has problems telling you where exactly
       something went wrong.

       -p     Enable  Perl/PHP mode, that is, do not consider presence $(, $),
	      $[ and $]	of a bracket imbalance.

       $ checkbrack /usr/lib/hxtools/bin/checkbrack | less -S
       #   () [] {}
       13  0  0	 1 foreach my $file (@ARGV) {
       14  0  0	 1     if (!-f $file) {	next; }
       15  0  0	 1     print "Displaying $file...0;
       16  0  0	 2     if (!open(IN, "<	$file")) {
       17  0  0	 2	   print "Error	opening	$file: $!0;
       18  0  0	 2	   next;
       19  0  0	 1     }

       The numbers at the front	are: line  number,  number  of	unclosed  left
       parentheses,  number of unclosed	left square brackets and number	of un-
       closed left square braces.

       At the end of line 19, we would need to close one more brace to make it
       syntactically valid code.

       The interesting thing of	this, that if GCC, Perl	or whatever outputs an
       error and you do	not figure out what it means --	that is	often the case
       with  missing  braces --	run checkbrack on the source file, skip	to the
       end, and	watch the brace	counts.

       Scroll up until the brace counts	seem normal (i.e. 0  open  braces)  at
       outside any function.
