=item B<-c>
causes Perl to check the syntax of the program and then exit without
-executing it. Actually, it I<will> execute C<BEGIN>, C<STOP>, and
+executing it. Actually, it I<will> execute C<BEGIN>, C<CHECK>, and
C<use> blocks, because these are considered as occurring outside the
execution of your program. C<INIT> and C<END> blocks, however, will
be skipped.
A colon-separated list of directories in which to look for Perl library
files before looking in the standard library and the current
-directory. If PERL5LIB is not defined, PERLLIB is used. When running
-taint checks (because the program was running setuid or setgid, or the
-B<-T> switch was used), neither variable is used. The program should
-instead say
+directory. Any architecture-specific directories under the specified
+locations are automatically included if they exist. If PERL5LIB is not
+defined, PERLLIB is used.
