validate - run many filetest checks on a tree

## SYNOPSIS

        use File::CheckTree;

        $warnings += validate( q{
    	/vmunix                 -e || die
    	/boot                   -e || die
    	/bin                    cd
    	    csh                 -ex
    	    csh                 !-ug
    	    sh                  -ex
    	    sh                  !-ug
    	/usr                    -d || warn "What happened to $file?\n"
        });

## DESCRIPTION

The validate() routine takes a single multiline string consisting of lines containing a filename plus a file test to try on it. (The file test may also be a "cd", causing subsequent relative filenames to be interpreted relative to that directory.) After the file test you may put `|| die` to make it a fatal error if the file test fails. The default is `|| warn`. The file test may optionally have a "!' prepended to test for the opposite condition. If you do a cd and then list some relative filenames, you may want to indent them slightly for readability. If you supply your own die() or warn() message, you can use $file to interpolate the filename.

Filetests may be bunched: "-rwx" tests for all of `-r`, `-w`, and `-x`. Only the first failed test of the bunch will produce a warning.

The routine returns the number of warnings issued.
