## NAME
       perlivp - Perl Installation Verification Procedure

## SYNOPSIS
       **perlivp **[**-p**] [**-v**] [**-h**]

## DESCRIPTION
       The **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 **perl **and its libraries have been
       installed correctly.  A correct installation is verified by output that looks like:

           ok 1
           ok 2

       etc.

## OPTIONS
### -h 
            Prints out a brief help message.

### -p 
            Gives a description of each test prior to performing it.

### -v 
            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.

## DIAGNOSTICS
       •   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.

       •   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.

       •   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.

       •   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.

       •   print "# Required module '$_' does not appear to be properly installed.\n";

           An attempt to "eval "require  $module""  failed,  even  though  the  list  of  extensions
           indicated that it should succeed.  Correct by conducting a proper installation.

       •   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 "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.

       •   print "# file",+($#missing == 0) ? '' : 's'," missing from installation:\n";

           One or more files turned up  missing  according  to  a  run  of  "[ExtUtils::Installed](https://www.chedong.com/phpMan.php/perldoc/ExtUtils%3A%3AInstalled/markdown)  ->
           validate()" over your installation.  Correct by conducting a proper installation.

       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.
