The Symbian Installation System provides a simple and consistent user
interface for installing applications, data, or configuration information to
EPOC devices. End users install components packaged in EPOC Installation
(sis
) files either from a PC, using the installer, or from an EPOC
Device, using the Add/remove
program.
Two tools are provided to enable developers to create installation files:
The Installation File Generator — creates the installation files from a specification provided in a package file.
The Certificate Generator — creates private/public key pairs, which are used by the Installation File Generator to digitally sign installation files.
The Sisar GUI tool provides a simple way to create .sis
files: for details see the
Sisar Guide. It is possible though to
write the required .pkg
files by hand, and compile them using
command-line tools, and this section contains the information to do so.
