Abstract: A method of storing version and product information of libraries used in the building of an executable file. For each library, a source file containing the version and product information is constructed, compiled and the resulting version object file is stored in the library. When the build of an executable occurs, the version object file for each of the libraries needed for the build is obtained and stored in a temporary area. A list is made of the names of the stored version object files and, when the executable is compiled, the list is submitted to the compiler command so that the version object files of each library are compiled into the executable file. In one alternative, a compound library formed from a selected set of libraries can be compiled into the executable. A utility program can be used to retrieve the stored version and product information in the executable.

Abstract: A system for preserving, generating, and merging different versions of a common module that utilizes a line file storing the text of every line in a version and addressing each line with a unique line identifier. Any desired version may be generated directly without creating intermediate versions. The unique line identifiers facilitate a merge operation that does not duplicate lines.
