Amiga Release 2 - Fixed up pager support in perldoc, now uses MultiView / More
or Type as found in that order.
You may overide the pager by setting the PAGER variable to the full path of the
new pager
eg:
setenv save PAGER MultiViewer:MultiViewer
NAME
 perlamiga - Perl under AmigaOS 4.1
NOTE
 This is a port of Perl 5.22.1, it is a fresh port and not in any way
 compatible with my previous ports of Perl 5.8 and 5.16.3. This means you
 will need to reinstall / rebuild any third party modules you have
 installed.
 newlib.library version 53.28 or greater is required.
SYNOPSIS
 Once perl is installed you can read this document in the following way
 sh -c "perldoc perlamiga"
 or you may read *as is*: either as README.amiga, or pod/perlamiga.pod.
DESCRIPTION
 Prerequisites for running Perl 5.22.1 under AmigaOS 4.1
 AmigaOS 4.1 update 6 with all updates applied as of 9th October 2013
 The most important of which is:
 newlib.library version 53.28 or greater
 AmigaOS SDK
 Perl installs into the SDK directory structure and expects many of
 the build tools present in the SDK to be available. So for the
 best results install the SDK first.
 abc-shell
 If you do not have the SDK installed you must at least have
 abc-shell installed or some other suitable sh port. This is
 required to run external commands and should be available as 'sh'
 in your path.
 Starting Perl programs under AmigaOS 4.1
 Perl may be run from the AmigaOS shell but for best results should be
 run under abc-shell. (abc-shell handles file globbing, pattern
 expansion, and sets up environment variables in the UN*Xy way that Perl
 expects.)
 For example:
 New Shell process 10
 10.AmigaOS4:> sh
 /AmigaOS4>perl path:to/myprog arg1 arrg2 arg3
 Abc-shell can also launch programs via the #! syntax at the start of the
 program file, it's best use the form #!SDK:Local/C/perl so that the
 AmigaOS shell may also find perl in the same way. AmigaOS requires the
 script bit to be set for this to work
 10.AmigaOS4:> sh
 /AmigaOS4>myprog arg1 arrg2 arg3
 Limitations of Perl under AmigaOS 4.1
 Nested Piped programs can crash when run from older abc-shells
 abc-shell version 53.2 has a bug that can cause crashes in the
 subprocesses used to run piped programs, if a later version is
 available you should install it instead.
 Incorrect or unexpected command line unescaping
 newlib.library 53.30 and earlier incorrectly unescape slashed
 escape sequences e.g. " \n \t etc requiring unusual extra
 escaping.
 Starting subprocesses via open has limitations
 open FH, "command |"
 Subprocesses started with open use a minimal popen() routine and
 therefore they do not return pids usable with waitpid etc.
 If you find any other limitations or bugs then let me know.
 Please report bugs in this version of perl to
 andy()broad.ology.org.uk in the first instance.
INSTALLATION
 This guide assumes you have obtained a prebuilt archive from
 os4depot.net.
 Unpack the main archive to a temporary location (RAM: is fine).
 Execute the provided install script from shell or via its icon.
 You must not attempt to install by hand.
 Once installed you may delete the temporary archive.
 This approach will preserve links in the installation without creating
 duplicate binaries.
 If you have the earlier ports perl 5.16 or 5.8 installed you may like to
 rename your perl executable to perl516 or perl58 or something similar
 before the installation of 5.22.1, this will allow you to use both
 versions at the same time.
Amiga Specific Modules
 Amiga::ARexx
 The Amiga::ARexx module allows you to easily create a perl based ARexx
 host or to send ARexx commands to other programs.
 Try "perldoc Amiga::ARexx" for more info.
 Amiga::Exec
 The Amiga::Exec module introduces support for Wait().
 Try "perldoc Amiga::Exec" for more info.
BUILDING
 To build perl under AmigaOS from the patched sources you will need to
 have a recent version of the SDK. Version 53.29 is recommended, earlier
 versions will probably work too.
 With the help of Jarkko Hietaniemi the Configure system has been tweaked
 to run under abc-shell so the recommend build process is as follows.
 stack 2000000
 sh Configure -de
 gmake
 This will build the default setup that installs under
 SDK:local/newlib/lib/
CHANGES
 August 2015
 Port to Perl 5.22
 Add handling of NIL: to afstat()
 Fix inheritance of environment variables by subprocesses.
 Fix exec, and exit in "forked" subprocesses.
 Fix issue with newlib's unlink, which could cause infinite loops.
 Add flock() emulation using IDOS->LockRecord thanks to Tony Cook
 for the suggestion.
 Fix issue where kill was using the wrong kind of process ID
 27th November 2013
 Create new installation system based on installperl links and
 Amiga protection bits now set correctly.
 Pod now defaults to text.
 File::Spec should now recognise an Amiga style absolute path as
 well as an Unix style one. Relative paths must always be Unix
 style.
 20th November 2013
 Configured to use SDK:Local/C/perl to start standard scripts
 Added Amiga::Exec module with support for Wait() and AmigaOS
 signal numbers.
 10th October 13
 First release of port to 5.16.3.
