Method and system for localizing a package

A localization tool is arranged to automatically localize a raw package for a target language, country or geographic region. The raw package is an executable binary stored in a specific location identified in a file system. The raw package includes data that identifies localization information. The localization tool uses the localization information to create a list of files to be localized in the target language, identify any strings to replace within each file, locate the files to be localized in the file system where the raw package is stored, and create any other parameters and functions required to localize the raw package. The raw package is localized by applying the target language, country or geographic region specific information to the files to be localized. The localized package is then stored in a target directory within the file system.

The method adopts cross lists as the data structure of a network diagram and arrays, structures and single linked lists as the solution to generate directly the data structure of a double-code network diagram with a detailed work list. A user is first asked to compile a detailed work list which then is read into the memory of a computer by a program; next, the program carries out automatic denomination for a tail node and a heat node of each process and automatic localization for the position of each node and finally transforms a complete detailed work list into a double-code network diagram document. The invention can not only avoid the frequent transformation of the network diagram and reduce the error probability, but also eliminate the trouble of the user for inputting the names of the tail node and head node of each process, thereby significantly improving the design efficiency of the network diagram and providing great convenience for the user in design of new network diagrams.
