|Purpose and scope of library|
The general purpose of this library is to provide C language procedures related to cartographic processes. Procedures for each of the processes will be strictly categorized and although they may share common subfunctions they will not intersect in scope.Current procedure categories consist of:
In addition to the library will be programs for usage of one or more library elements:
All libproject software will be distributed with configure and associated tools for installation on Linux/Unix class platforms. Shared library will be installed when applicable. Sorry, no Microsoft support available.
