8.96. File::CheckTree

Runs file tests on a set of files. Exports one function, validate, which takes a single multiline string as input. Each line of the string contains a filename plus a test to run on the file. The test can be followed with || die to make it a fatal error if it fails. The default is || warn. Prepending ! to the test reverses the sense of the test. You can group tests (e.g., -rwx); only the first failed test of the group produces a warning. For example:

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

Available tests include all the standard Perl file-test operators except -t, -M, -A, and -C. Unless it dies, validate returns the number of warnings issued.
