A package abbreviation is a short name for a package that is defined by the PKG parameter in the pkginfo file. A package abbreviation must have these characteristics:
The abbreviation must consist of alphanumeric characters. The first character cannot be a number.
The abbreviation cannot exceed 32 characters in length.
The abbreviation cannot be one of the reserved abbreviations: install, new, or all.
The first four characters should be unique to your company. For example, packages built by Sun MicrosystemsTM all have “SUNW” as the first four characters of their package abbreviation.
An example of a package abbreviation entry in a pkginfo file is PKG=SUNWcadap.
