Podify the remaining README.platform files;

merge README.plan9 and plan9/perlplan9.pod;
delete plan9/perlplan9.* (the perlplan.doc needs to
be regenerated in Plan 9); make the =head1 and =head2
in the README.platform to be a little more verbose
(skipped README.os2 not to anger Ilya) so that they
look better in the toc; regen toc.

+=head1 NAME
+
+perlplan9 - Plan 9-specific documentation for Perl
+
+=head1 DESCRIPTION
+
+These are a few notes describing features peculiar to
+Plan 9 Perl. As such, it is not intended to be a replacement
+for the rest of the Perl 5 documentation (which is both 
+copious and excellent). If you have any questions to 
+which you can't find answers in these man pages, contact 
+Luther Huffman at lutherh@stratcom.com and we'll try to 
+answer them.
+
+=head2 Invoking Perl
+
+Perl is invoked from the command line as described in 
+L<perl>. Most perl scripts, however, do have a first line 
+such as "#!/usr/local/bin/perl". This is known as a shebang 
+(shell-bang) statement and tells the OS shell where to find 
+the perl interpreter. In Plan 9 Perl this statement should be 
+"#!/bin/perl" if you wish to be able to directly invoke the 
+script by its name.
+     Alternatively, you may invoke perl with the command "Perl"
+instead of "perl". This will produce Acme-friendly error
+messages of the form "filename:18".
+
+Some scripts, usually identified with a *.PL extension, are 
+self-configuring and are able to correctly create their own 
+shebang path from config information located in Plan 9 
+Perl. These you won't need to be worried about.
+
+=head2 What's in Plan 9 Perl
+
+Although Plan 9 Perl currently only  provides static 
+loading, it is built with a number of useful extensions. 
+These include Opcode, FileHandle, Fcntl, and POSIX. Expect 
+to see others (and DynaLoading!) in the future.
+
+=head2 What's not in Plan 9 Perl
+
+As mentioned previously, dynamic loading isn't currently 
+available nor is MakeMaker. Both are high-priority items.
+
+=head2 Perl5 Functions not currently supported in Plan 9 Perl
+
+Some, such as C<chown> and C<umask> aren't provided 
+because the concept does not exist within Plan 9. Others,
+such as some of the socket-related functions, simply
+haven't been written yet. Many in the latter category 
+may be supported in the future.
+
+The functions not currently implemented include:
+
+    chown, chroot, dbmclose, dbmopen, getsockopt, 
+    setsockopt, recvmsg, sendmsg, getnetbyname, 
+    getnetbyaddr, getnetent, getprotoent, getservent, 
+    sethostent, setnetent, setprotoent, setservent, 
+    endservent, endnetent, endprotoent, umask
+
+There may be several other functions that have undefined 
+behavior so this list shouldn't be considered complete.
+
+=head2 Signals in Plan 9 Perl
+
+For compatibility with perl scripts written for the Unix 
+environment, Plan 9 Perl uses the POSIX signal emulation
+provided in Plan 9's ANSI POSIX Environment (APE). Signal stacking
+isn't supported. The signals provided are:
+
+    SIGHUP, SIGINT, SIGQUIT, SIGILL, SIGABRT,
+    SIGFPE, SIGKILL, SIGSEGV, SIGPIPE, SIGPIPE, SIGALRM, 
+    SIGTERM, SIGUSR1, SIGUSR2, SIGCHLD, SIGCONT,
+    SIGSTOP, SIGTSTP, SIGTTIN, SIGTTOU
+
+=head1 COMPILING AND INSTALLING PERL ON PLAN 9
+
 WELCOME to Plan 9 Perl, brave soul!
-   This is a preliminary alpha version of Plan 9 Perl. Still to be implemented are MakeMaker and DynaLoader. Many perl commands are missing or currently behave in an inscrutable manner. These gaps will, with perserverance and a modicum of luck, be remedied in the near future.To install this software:
 
-   1. Create the source directories and libraries for perl by running the plan9/setup.rc command (i.e., located in the plan9 subdirectory). Note: the setup routine assumes that you haven't dearchived these files into /sys/src/cmd/perl. After running setup.rc you may delete the copy of the source you originally detarred, as source code has now been installed in /sys/src/cmd/perl. If you plan on installing perl binaries for all architectures, run "setup.rc -a".
-After 
-   2. Making sure that you have adequate privileges to build system software, from /sys/src/cmd/perl/5.00301 run:
-mk install
-     If you wish to install perl versions for all architectures (68020, mips, sparc and 386) run:
-mk installall

+
+This perl distribution comes with a tremendous amount of
+documentation. To add these to the built-in manuals that come with
+Plan 9, from /sys/src/cmd/perl/5.00301 (adjust version appropriately)
+run:
+
+	mk man
 
-INSTALLING DOCUMENTATION

-mk man
 To begin your reading, start with:
-man perl
