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