Package Specification

---

The package specification is the first item in the file and is declared using the `package' keyword. By default, this is set to the name of the ASN.1 module that is being compiled. However, this can be modified by using the -pkgpfx and -pkgname command line options. The -pkgpfx option adds the specified prefix before the module name. For example, if an ASN.1 module named `Employee' is being compiled and `-pkgpfx test.' is specified on the command line, the package name in the generated source files would be `test.Employee'. The -pkgname switch takes this a step further. It allows specification of the full package name. In the sample specification above, `-pkgpfx sample_ber.' was specified on the compiler command line.

Standard import statements are added for the ASN1C Java run-time classes and Java utility classes. Import statements may also be added for items imported from other ASN.1 modules if they don't exist within the package being generated.
