BLURB

 AFS::PAG provides the standard PAG and token manipulation functions
 setpag and unlog to Perl programs as a native module.  It also provides
 the hasafs and haspag functions to detect whether AFS is running and
 whether the current process is in a PAG.  Unlike the more general AFS
 module, it will build with any recent OpenAFS, Heimdal's libkafs, or on
 Linux without any AFS libraries at all.

DESCRIPTION

 AFS is a distributed file system allowing cross-platform sharing of
 files among multiple computers.  It associates client credentials
 (called AFS tokens) with a Process Authentication Group, or PAG.
 AFS::PAG makes available in Perl the PAG manipulation functions provided
 by the libkafs or libkopenafs libraries.

 With the functions provided by this module, a Perl program can detect
 whether AFS is available on the local system and whether it is currently
 running inside a PAG.  It can also create a new PAG and put the current
 process in it, and remove any AFS tokens in the current PAG.

 This module doesn't provide a direct way to obtain new AFS tokens, only
 to create a new PAG so that any obtained tokens are isolated from other
 processes on the system and can be inherited by child processes.

REQUIREMENTS

 Perl 5.10.1 or later, the Config::AutoConf module, and a C compiler are
 required to build this module.  On any platform other than Linux, either
 the kafs library (from Heimdal) or the kopenafs library (from recent
 versions of OpenAFS) are also required.

 The following additional Perl modules will be used by the test suite if
 present:

     IPC::System::Simple
     Test::MinimumVersion
     Test::Perl::Critic
     Test::Pod
     Test::Pod::Coverage
     Test::Spelling
     Test::Strict
     Test::Synopsis

 All are available on CPAN.  Those tests will be skipped if the modules
 are not available.

 To enable tests that may be sensitive to the local environment or that
 produce a lot of false positives without uncovering many problems, set
 RRA_MAINTAINER_TESTS to a true value.

BUILDING AND INSTALLATION

 AFS::PAG uses Module::Build and can be installed using the same process
 as any other Module::Build module:

     perl Build.PL
     ./Build
     ./Build test
     ./Build install

 If your libkafs or libkopenafs libraries are in a path that's not
 searched by your linker by default, pass them to Build.PL using the
 --extra-linker-flags option, as in:

     perl Build.PL --extra-linker-flags '-L/opt/openafs/lib'

 You will have to run the last command as root unless you're installing
 into a local Perl module tree in your home directory.

SUPPORT

 The AFS::PAG web page at:

     http://www.eyrie.org/~eagle/software/afs-pag/

 will always have the current version of this package, the current
 documentation, and pointers to any additional resources.

 For bug tracking, this package uses the CPAN bug tracker at:

     https://rt.cpan.org/Public/Dist/Display.html?Name=AFS-PAG

 I welcome bug reports and patches for this package at [email protected] or
 via the CPAN bug tracker.  However, please be aware that I tend to be
 extremely busy and work projects often take priority.  I'll save your
 mail and get to it as soon as I can, but it may take me a couple of
 months.
