#   software_local.cf - Application Deployment From Directory Repository
#
#   NOTE: Windows needs to support WMI queries about installed msi files
#         in order for Cfengine to detect them. On Windows 2003,
#         go to Control Panel -> Add/Remove Programs -> 
#         Windows Components -> Mgmnt and Monitoring Tools and check
#         WMI Windows Installer Provider.
#
#   NOTE: Naming conventions are important when updating packages.
#         By default, Cfengine expects "name-version-arch.msi" 
#         on Windows, where name is lowercase, and arch is 
#         i686 or x86_64. No spaces should be included in the filename.
#         The Caption and Version fields inside the msi package
#         are important. They must correspond to the file name as 
#         follows: name = lowercase(spacetodash(Caption)), 
#         version = Version. For any msi-file, use InstEd 
#         (www.instedit.com) to check/modify the 
#         Caption and Version fields 
#         (Tables->Property->ProductName/ProductVersion).
#
#         For example, ProductName "Cfengine Nova" with ProductVersion
#         "1.1.2" for 32-bit Windows will correspond to the filename
#         "cfengine-nova-1.1.2-i686.msi".
