For more informations look at: +http://www.symbian.com/ + +This is a port of perl to the epocemx SDK by Eberhard Mattes, which +itself uses the SDK by symbian. Essentially epocemx it is a POSIX +look alike environment for the EPOC OS. For more information look at: +http://epocemx.sourceforge.net/ + +perl and epocemx runs on Epoc Release 5 machines: Psion 5mx, 5mx Pro, +Psion Revo, Psion Netbook and on the Ericsson M128. It may run on Epoc +Release 3 Hardware (Series 5 classic), too. For more information about +this hardware please refer to http://www.psion.com/ + +Vendors which like to have support for their devices are free to send +me a sample. + +=head1 INSTALLING PERL ON EPOC + +You can download a ready-to-install version from +http://www.oflebbe.de/oflebbe/perl/ + +You will need at least ~6MB free space in order to install and run perl. + +Please install the emxusr.sis package from +http://epocemx.sourceforge.net/ first. + +Install perl.sis on the EPOC machine. If you do not know how to do +that, consult your PsiWin documentation. + +Perl itself and its standard library is using 4 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 + +Please use the epocemx shell to start perl. perl integrates with the +conventions of epocemx. + +=head2 Editors on Epoc + +A suitable text editor can be downloaded from symbian +http://www.symbian.com/developer/downloads/files/editor.zip + +=head2 Features of Perl on Epoc + +The built-in function EPOC::getcwd returns the current directory. + +=head2 Restrictions of Perl on Epoc + +Features are left out, because of restrictions of the POSIX support in +EPOC: + +=over 4 + +=item * + +socket IO is only implemented poorly. You can only use sysread and +syswrite on them. The commands read, write, print, <> do not work for +sockets. This may change iff epocemx supports sockets. + +=item * + +kill, alarm and signals. Do not try to use them. This may be +impossible to implement on EPOC. + +=item * + +select is missing. + +=item * + +binmode does not exist. (No CR LF to LF translation for text files) + +=item * + +EPOC does not handle the notion of current drive and current +directory very well (i.e. not at all, but it tries hard to emulate +one).
