Editing Synology package files (section)

===Installation process===
When uploading a .spk file, the file will be uploaded to a temporary directory (can be found in the environment variable 'SYNOPKG_PKGINST_TEMP_DIR, during the running of the 'preinst' script). Normally, this will be in a '@tmp' dir on the root of volume1. It will be unpacked (not the package.tgz yet) and script 'preinst' will be called. After that, the user has to select a volume to install to.Under the root of this volume, a '@appstore will be created, if this directory not exists already. In this directory, a directory using the name given in the INFO file as value of key 'package' will be created (this name can also be found in the SYNOPKG_PKGNAME environment variable). The 'package.tgz' will be uncompressed and unpacked under that directory (which can be found in environment variable 'SYNOPKG_PKGDEST'. After this, in the directory /var/packages will be a directory created by the name of the package. In this directory there will be the scripts dir and INFO file of the package. Also a link called 'target' which will point to the unpacked directory under your @appstore dir in the destination volume. The directories under /var/packages/ will be used by the packagemanager. Finally, the script 'postinst' will be called and all temporary files will be removed.

Note that the 'adminport' option under INFO is a bit strange. It will only be used when displaying management page URL ''if the program status returns 'running' ''. The packagemanager will automaticly create the url out of '<nowiki>http://</nowiki>' +hostname+':'+adminport. There is no way to change that url other then the port number.
