-This is a port of perl to EPOC. It runs on the Psion Series 5, 5mx,
-5mx Pro, Psion Revo and on the Ericson M128. I have no report about
-the Psion Netbook or the S7. For information about this hardware

+=head1 INSTALLING PERL ON EPOC
+
+You can download a ready-to-install version from
+http://www.science-computing.de/o.flebbe/perl. You may find other
+versions with some CPAN modules included at this location.
-=====================================================================
-Installation/Usage
-=====================================================================
+You will need at least ~4MB free space in order to install and run
+perl.
-You will need ~4MB free space in order to install and run perl.
+Install perl.sis on the EPOC machine. If you do not know how to do
+that, consult your PsiWin documentation.
-Install perl.sis on the EPOC machine (most likely a PSION Series 5,
-5mx). If you do not know how to do that, you are on your own.
+Perl itself and its standard library is using 2.5 MB disk space.
+Unicode support and some other modules are left out. (For details,
+please look into epoc/createpkg.pl). If you like to use these modules,
+you are free to copy them from a current perl release.

+=head1 STARTING PERL ON EPOC
-Get ESHELL from symbian:
-http://developer.epocworld.com/downloads/progs/Eshell.zip
+For ER5 machines, you can get the software Perlstart
+http://www.science-computing.de/o.flebbe/perl. It contains file
+recognizers for files with the extension .pl and .pm. With it you can
+start perl with a double click on the camel icon. Be sure to configure
+the perl installation drive first. You can even provide a script with
+a special commandline, if needed.
-Now you can enter: perl -de 0 in order to run the perl debugger. If
-you are leaving perl, you get into the system screen. You have to
-switch back manually to ESHELL. When perl is running, you will see
-a task with the name STDOUT in the task list.
+Alternatively you can use the epocemx shell
-======================================================================
-IO Redirection
-======================================================================
+If you have an ER3 machine (i.e. a PSION 5), you may have to supply the
+full path to the perl executable C:\system\programs\perl.exe.
+
+If you need to set the current directory of perl, please use the
+command line switch '-x'. See L<perlrun> for details.
+
+=head1 STOPPING PERL ON EPOC
+
+You can stop a running perl process in the task list by closing the
+application `STDOUT'. You can use the kill command in the epocemx
+shell to kill perl.
+
+=head1 USING PERL ON EPOC

+=head2 I/O Redirection on Epoc
You can redirect the output with the UNIX bourne shell syntax (this is
built into perl rather then eshell) For instance the following command
perl test.pl >stdout_file <stdin_file 2>stderr_file
-Alternativly you can use 2>&1 in order to add the standard error
+Alternatively you can use 2>&1 in order to add the standard error
output to stdout.
-======================================================================
-PATH Names
-======================================================================
+=head2 PATH Names on Epoc
ESHELL looks for executables in ?:/System/Programs. The SIS file
installs perl in this special folder directory. The default drive and
path are the same as folder the executable resides. The EPOC
filesystem is case-preserving, not case-sensitive.
-EPOC uses the ?: syntax for establishing a search order: First in C: (RAM),
-then on D: (CF Card) and last in Z: (ROM).
+The EPOC estdlib uses the ?: syntax for establishing a search order:
+First in C: (RAM), then on D: (CF Card, if present) and last in Z:
+(ROM). For instance ?:\a.txt searches for C:\a.txt, D:\a.txt (and
+Z:\a.txt)
-The perl @INC search path is now implemented with '?:'. Your perl
-executable can now live on a different drive than the perl library or
-even your scripts.
+The perl @INC search path is implemented with '?:'. Your perl
+executable can live on a different drive than the perl library or even
+your scripts.
ESHELL paths have to be written with backslashes '\', file arguments
to perl with slashes '/'. Remember that I/O redirection is done
perl.exe C:/test.pl >C:/output.txt
-You can automatically search for file on all EPOC drives with a ? as
-the driver letter. For instance ?:\a.txt searches for C:\a.txt,
-D:\b.txt (and Z:\a.txt).
