I have just uploaded ports of cflow and cscope to the VOS anonymous ftp site, which is at ftp://ftp.stratus.com/pub/vos/vos.html.

The cflow tool analyzes a collection of C source files and prints a graph that chars the control flow within the program. It can help you understand an unfamiliar program that you have taken over.

The cscope tool is a source code browser; mostly for C and C++, but it can work on other file types as well.  It simplifies the task of searching source code for symbols, constants, functions, and so on. You can find out who calls a particular function, or which other functions the current function calls, or you can just search all code for a text string. It is a glorified text editor, if you will.

You can download the source code directly from ftp://ftp.stratus.com/pub/vos/posix/ga/v-series/v-series.html.  The packages come with instructions on how to build the binaries and install them on your system. While these are not official Stratus products, if you have any questions or comments, please send them my way.

If there are other packages you’d like to see ported, please let me know.
