<H1>The Ensymble developer utilities for Symbian OS</H1>
13
This is the Ensymble developer utilities for
14
<A HREF="http://www.symbian.com">Symbian OS™</A>, a collection of
15
<A HREF="http://www.python.org">Python®</A> modules and command line
16
programs for Symbian OS software development.
19
Current focus of Ensymble development is to provide useful tools for making
20
<A HREF="http://sourceforge.net/projects/pys60">Python for S60</A> programs.
21
Supported functions include generation of SIS (installation) packages,
22
merging several SIS packages into one, (re-)signing existing SIS packages
23
and modifying extension DLL headers. Support for other Symbian OS software
24
development tasks will follow.
27
A long term goal of Ensymble is to provide a cross-platform, open-source
28
way to do Symbian OS software development, supporting Symbian OS
29
versions 9.1 and later. The original tools by Symbian are closed source
30
and only available for the Windows® operating system. Ensymble is
31
under the GNU <A HREF="http://www.gnu.org/licenses/gpl.html">GPL</A> license.
38
<LI>Most Unix-like operating systems, tested on Linux and OS X</LI>
39
<LI>Windows® NT, 2000 or XP, tested on XP</LI>
41
<LI>Python v2.2 or greater, tested on Python v2.2, v2.3, v2.4 and v2.5</LI>
43
The <A HREF="http://www.openssl.org">OpenSSL</A> command line tool:
45
<LI>OpenSSL is pre-installed on most Linux systems and on OS X.</LI>
46
<LI>For Windows, the <A HREF="http://www.stunnel.org/download/binaries.html">Stunnel
47
OpenSSL binaries</A> are recommended.</LI>
52
Ensymble targets Symbian OS v9.1 and later. For Nokia phones, this means
53
S60 3rd Edition. 1st and 2nd Edition phones are not directly
54
supported by Ensymble. A list of editions for Nokia phones is available from
55
<A HREF="http://www.forum.nokia.com/devices/matrix_s60_1.html">Forum Nokia</A>.
56
(See <A HREF="http://www.nbl.fi/jussi.ylanen/py2sisng.html">py2sisng</A> for a
57
cross-platform version of py2sis, compatible with S60 1st and 2nd Edition.)
60
The py2sis command of Ensymble produces installation packages (SIS) for
61
<A HREF="http://sourceforge.net/projects/pys60">Python for S60</A> version
62
1.4.0 and later. Version 1.4.0 of Python for S60 is the first officially
63
signed release from Nokia. Although packages generated with Ensymble also
64
work with PyS60 from v1.3.8 upto v1.3.23, a harmless warning is generated
65
during installation for a missing Python for S60 component.
68
<B>NOTE:</B> PyS60 versions 1.3.20 and older require that SIS files
69
generated by Ensymble are installed into main phone memory instead
71
<A HREF="http://sourceforge.net/tracker/index.php?func=detail&aid=1579521&group_id=154155&atid=790646">bug</A> has
72
been corrected in version 1.3.21 of PyS60.
76
Ensymble pre-<A HREF="http://effbot.org/zone/squeeze.htm">squeezed</A> versions
77
are ready to use. Just copy the file to a suitable place (on command search
78
path) and start using it!

<LI>Implemented --heapsize option for the py2sis and altere32 commands.
101
Sometimes the default heap maximum limit of one megabyte is not enough, for
102
example when handling large pictures from the built-in camera.</LI>
103
<LI>Implemented an --extrasdir option for the py2sis command. It allows
104
flexible placement of extra files, just like the simplesis command does.</LI>
105
<LI>Added support for PKCS#8 format private keys. Some people have
106
received these types of keys from Symbian.</LI>
