checkbrack — check parenthesis and bracket count

       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.

       $ 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 unclosed 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.
