+#  NAME:              The internal name of the package.
+#                     Note that all synocoummunity packages use lowercase names.
+#                     This enables to have concurrent packages with synology.com, that use 
+#                     package names starting with upper case letters. 
+#                     (e.g. Mono => synology.com, mono => synocommunity.com)
+#  SPK_FILE_NAME:     The full spk name with folder, package name, arch, tc- and package version.
+#  SPK_CONTENT:       List of files and folders that are added to package.tgz within the spk file.
+#  DSM_SCRIPT_FILES:  List of script files that are in the scripts folder within the spk file.
