+C<miniperl> is built. This is a single executable (without DLL), intended
+to run on Win32, and it will facilitate remaining build process; all binaries
+built after it are foreign and should not run locally.
+
+C<miniperl> is built using ../win32/Makefile; this is part of normal
+build process invoked as dependency from wince/Makefile.ce
+

+After C<miniperl> is built, 'configpm' is invoked to create right Config.pm
+in right place and its corresponding Cross.pm.
 
-  http://perlce.sourceforge.net
+Unlike Win32 build, miniperl will not have Config.pm of host within reach;
+it rather will use Config.pm from within cross-compilation directories.
 
-There should also be pre-built binaries there.
+File Cross.pm is dead simple: for given cross-architecture places in @INC
+a path where perl modules are, and right Config.pm in that place.
 
-Don't be confused by large size of downloaded distribution or constructed
-binaries: entire distribution could be large for WinCE ideology, but
-you may strip it at your wish and use only required parts.
+That said, C<miniperl -Ilib -MConfig -we 1> should report an error, because
+it can not find Config.pm. If it does not gives an error -- wrong Config.pm
+is substituted, and resulting binaries will be a mess.
+
+C<miniperl -MCross -MConfig -we 1> should run okay, and it will provide right
+Config.pm for further compilations.

+During extensions build phase, a script C<./win32/buldext.pl> is invoked,

+All invokes of Makefile.PL are provided with C<-MCross> so to enable cross-
+compile.

+=head1 Using Perl on WinCE
+
+=head2 DESCRIPTION
+
+PerlCE is currently linked with a simple console window, so it also
+works on non-hpc devices.
+
+The simple stdio implementation creates the files stdin.txt,
+stdout.txt and stderr.txt, so you might examine them if your
+console has only a liminted number of cols.
+
+When exitcode is non-zero, a message box appears, otherwise the
+console closes, so you might have to catch an exit with
+status 0 in your program to see any output.
+
+stdout/stderr now go into the files /perl-stdout.txt and
+/perl-stderr.txt.
+
+=head2 LIMITATIONS
+
+No fork(), pipe(), popen() etc.
+
+=head2 ENVIRONMENT
+
+All environment vars must be stored in HKLM\Environment as
+strings. They are read at process startup.
+
+	PERL5LIB	- Usual perl lib path (semi-list).
+	PATH		- Semi-list for executables.
+	TMP		- Tempdir.
+	UNIXROOTPATH	- Root for accessing some special files,
+			  i.e. /dev/null, /etc/services.
+	ROWS/COLS	- Rows/cols for console.
+	HOME		- Home directory.
+	CONSOLEFONTSIZE - Size for console font.
+
+You can set these with cereg.exe, a (remote) registry editor
+or via the PerlIDE.
+
+=head2 REGISTRY
+
+To start perl by clicking on a perl source file, you have
+to make the according entries in HKCR (see wince-reg.bat).
+cereg.exe (which must be executed on a desktop pc with
+ActiveSync) is reported not to work on some devices.
+You have to create the registry entries by hand using a 
+registry editor.
+
+=head2 PERLFILES
+
+The following files are a reasonable minimum if you want to do
+some socket stuff:
+
+	./auto
+	./auto/DynaLoader
+	./auto/DynaLoader/autosplit.ix
+	./auto/DynaLoader/dl_expandspec.al
+	./auto/DynaLoader/dl_findfile.al

+	./auto/IO
+	./auto/IO/IO.bs
+	./auto/IO/IO.dll

+	./Socket.pm
+	./strict.pm
+	./Symbol.pm
+	./warnings
+	./warnings/register.pm
+	./warnings.pm
+	./XSLoader.pm
+
+=head2 XS
+
+The following Win32-Methods are built-in:
+
+	newXS("Win32::GetCwd", w32_GetCwd, file);
+	newXS("Win32::SetCwd", w32_SetCwd, file);
+	newXS("Win32::GetTickCount", w32_GetTickCount, file);
+	newXS("Win32::GetOSVersion", w32_GetOSVersion, file);
+	newXS("Win32::IsWinNT", w32_IsWinNT, file);
+	newXS("Win32::IsWin95", w32_IsWin95, file);
+	newXS("Win32::IsWinCE", w32_IsWinCE, file);
+	newXS("Win32::CopyFile", w32_CopyFile, file);
+	newXS("Win32::Sleep", w32_Sleep, file);
+	newXS("Win32::MessageBox", w32_MessageBox, file);
+	newXS("Win32::GetPowerStatus", w32_GetPowerStatus, file);
+	newXS("Win32::GetOemInfo", w32_GetOemInfo, file);
+	newXS("Win32::ShellEx", w32_ShellEx, file);
+
+=head2 BUGS
+
+Opening files for read-write is currently not supported if
+they use stdio (normal perl file handles).
+
+If you find bugs or if it does not work at all on your
+device, send mail to the address below. Please report
+the details of your device (processor, ceversion, 
+devicetype (hpc/palm/pocket)) and the date of the downloaded
+files. 
+
+=head2 INSTALLATION
+
+Currently installation instructions are at L<http://perlce.sourceforge.net/>.
+
+After installation & testing processes will stabilize, information will
+be more precise.
