==============================================================================================

Convenience script for creating signed packages you can install on your phone.

Usage: createpackage.pl [options] templatepkg [target]-[platform] [certificate key [passphrase]]

Where supported options are as follows:

     [-i|install]            = Install the package right away using PC suite.

     [-p|preprocess]         = Only preprocess the template .pkg file.

     [-c|certfile <file>]    = The file containing certificate information for signing.

                               The file can have several certificates, each specified in

                               separate line. The certificate, key and passphrase in line

                               must be ';' separated. Lines starting with '#' are treated

                               as a comments. Also empty lines are ignored. The paths in

                               <file> can be absolute or relative to <file>.

     [-u|unsigned]           = Preserves the unsigned package.

     [-o|only-unsigned]      = Creates only unsigned package.

     [-s|stub]               = Generates stub sis for ROM.

     [-n|sisname <name>]     = Specifies the final sis name.

Where parameters are as follows:

     templatepkg             = Name of .pkg file template

     target                  = Either debug or release

     platform                = One of the supported platform

                               winscw | gcce | armv5 | armv6 | armv7

     certificate             = The certificate file used for signing

     key                     = The certificate's private key file

     passphrase              = The passphrase of the certificate's private key file

Example:

     createpackage.pl fluidlauncher_template.pkg release-armv5

Example with certfile:

     createpackage.pl -c=mycerts.txt fluidlauncher_template.pkg release-armv5

     Content of 'mycerts.txt' must be something like this:

        # This is comment line, also the empty lines are ignored

        rd.cer;rd-key.pem

        .\\cert\\mycert.cer;.\\cert\\mykey.key;yourpassword

        X:\\QtS60\\s60installs\\selfsigned.cer;X:\\QtS60\\s60installs\\selfsigned.key

If no certificate and key files are provided, either a RnD certificate or

a self-signed certificate from QtDir\\src\\s60installs directory is used.

In the latter case the resulting package will also be automatically patched

using patch_capabilities.pl script, which makes it unsuitable for distribution.

Always specify certificates explicitly if you wish to distribute your package.
