+=head1 NAME
+
+B<perlivp> - Perl Installation Verification Procedure
+
+=head1 SYNOPSIS
+
+B<perlivp> [B<-p>] [B<-v>] [B<-h>]
+
+=head1 DESCRIPTION
+
+The B<perlivp> program is set up at Perl source code build time to test the
+Perl version it was built under. It can be used after running:
+
+ make install
+
+(or your platform's equivalent procedure) to verify that B<perl> and its
+libraries have been installed correctly. A correct installation is verified
+by output that looks like:
+
+ ok 1
+ ok 2
+
+etc.
+
+=head1 OPTIONS
+
+=over 5
+
+=item B<-h> help
+
+Prints out a brief help message.
+
+=item B<-p> print preface
+
+Gives a description of each test prior to performing it.
+
+=item B<-v> verbose
+
+Gives more detailed information about each test, after it has been performed.
+Note that any failed tests ought to print out some extra information whether
+or not -v is thrown.
+

+
+=head1 DIAGNOSTICS
+
+=over 4
+
+=item * print "# Perl binary `$perlpath' does not appear executable.\n";
+
+Likely to occur for a perl binary that was not properly installed.
+Correct by conducting a proper installation.
+
+=item * print "# Perl version `$]' installed, expected $ivp_VERSION.\n";
+
+Likely to occur for a perl that was not properly installed.
+Correct by conducting a proper installation.
+
+=item * print "# Perl \@INC directory `$_' does not appear to exist.\n";
+
+Likely to occur for a perl library tree that was not properly installed.
+Correct by conducting a proper installation.
+
+=item * print "# Needed module `$_' does not appear to be properly installed.\n";
+
+One of the two modules that is used by perlivp was not present in the
+installation. This is a serious error since it adversely affects perlivp's
+ability to function. You may be able to correct this by performing a
+proper perl installation.
+
+=item * print "# Required module `$_' does not appear to be properly installed.\n";
+
+An attempt to C<eval "require $module"> failed, even though the list of
+extensions indicated that it should succeed. Correct by conducting a proper
+installation.
+
+=item * print "# Unnecessary module `bLuRfle' appears to be installed.\n";
+
+This test not coming out ok could indicate that you have in fact installed
+a bLuRfle.pm module or that the C<eval " require \"$module_name.pm\"; ">
+test may give misleading results with your installation of perl. If yours
+is the latter case then please let the author know.
+
+=item * print "# file",+($#missing == 0) ? '' : 's'," missing from installation:\n";
+
+One or more files turned up missing according to a run of
+C<ExtUtils::Installed -E<gt> validate()> over your installation.
+Correct by conducting a proper installation.
+
+=item * print "# Perl header `$_' does not appear to be properly installed.\n";
+
+Correct by running B<h2ph> over your system's C header files. If necessary,
+edit the resulting *.ph files to eliminate perl syntax errors.
+
+=back
+
+For further information on how to conduct a proper installation consult the
+INSTALL file that comes with the perl source and the README file for your
+platform.
