-=head1 NAME
-
-validate - run many filetest checks on a tree
-
-=head1 SYNOPSIS
-
- use File::CheckTree;
-
- $num_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"
- });
-
-=head1 DESCRIPTION
-
-The validate() routine takes a single multiline string consisting of
-directives, each 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 C<|| die> to make it a fatal error if the file test fails.
-The default is C<|| 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 C<-r>, C<-w>, and C<-x>.
-Only the first failed test of the bunch will produce a warning.
-
-The routine returns the number of warnings issued.
-
-=head1 AUTHOR
-
-File::CheckTree was derived from lib/validate.pl which was
-written by Larry Wall.
-Revised by Paul Grassie <F<grassie@perl.com>> in 2002.
-
-=head1 HISTORY
-
-File::CheckTree used to not display fatal error messages.
-It used to count only those warnings produced by a generic C<|| warn>
-(and not those in which the user supplied the message). In addition,
-the validate() routine would leave the user program in whatever
-directory was last entered through the use of "cd" directives.
-These bugs were fixed during the development of perl 5.8.
-The first fixed version of File::CheckTree was 4.2.
