=head1 THE PERL MODULE LIBRARY
-A number of modules are included the Perl distribution. These are
-described below, and all end in F<.pm>. You may also discover files in
-the library directory that end in either F<.pl> or F<.ph>. These are old
-libraries supplied so that old programs that use them still run. The
-F<.pl> files will all eventually be converted into standard modules, and
-the F<.ph> files made by B<h2ph> will probably end up as extension modules
-made by B<h2xs>. (Some F<.ph> values may already be available through the
-POSIX module.) The B<pl2pm> file in the distribution may help in your
-conversion, but it's just a mechanical process and therefore far from
-bulletproof.
+Many modules are included the Perl distribution. These are described
+below, and all end in F<.pm>. You may discover compiled library
+file (usually ending in F<.so>) or small pieces of modules to be
+autoloaded (ending in F<.al>); these were automatically generated
+by the installation process. You may also discover files in the
+library directory that end in either F<.pl> or F<.ph>. These are
+old libraries supplied so that old programs that use them still
+run. The F<.pl> files will all eventually be converted into standard
+modules, and the F<.ph> files made by B<h2ph> will probably end up
+as extension modules made by B<h2xs>. (Some F<.ph> values may
+already be available through the POSIX, Errno, or Fcntl modules.)
+The B<pl2pm> file in the distribution may help in your conversion,
+but it's just a mechanical process and therefore far from bulletproof.
=head2 Pragmatic Modules
-They work somewhat like pragmas in that they tend to affect the compilation of
-your program, and thus will usually work well only when used within a
-C<use>, or C<no>. Most of these are locally scoped, so an inner BLOCK
-may countermand any of these by saying:
+They work somewhat like compiler directives (pragmata) in that they
+tend to affect the compilation of your program, and thus will usually
+work well only when used within a C<use>, or C<no>. Most of these
+are lexically scoped, so an inner BLOCK may countermand them
+by saying:
no integer;
no strict 'refs';
+ no warnings;
which lasts until the end of that BLOCK.
-Unlike the pragmas that effect the C<$^H> hints variable, the C<use
-vars> and C<use subs> declarations are not BLOCK-scoped. They allow
-you to predeclare a variables or subroutines within a particular
-I<file> rather than just a block. Such declarations are effective
-for the entire file for which they were declared. You cannot rescind
-them with C<no vars> or C<no subs>.
+Some pragmas are lexically scoped--typically those that affect the
+C<$^H> hints variable. Others affect the current package instead,
+like C<use vars> and C<use subs>, which allow you to predeclare a
+variables or subroutines within a particular I<file> rather than
+just a block. Such declarations are effective for the entire file
+for which they were declared. You cannot rescind them with C<no
+vars> or C<no subs>.
The following pragmas are defined (and have their own documentation).
