Version 6.17 of the Linux manual-page collection has been released. Along with a long list of updates to the man pages themselves, it includes some new utility programs of interest. The grepc(1) program is something that originated in this project, as it helped me find code quickly in glibc and the Linux kernel. However, I've found it incredibly useful outside of this project. I'll take some space to announce it, as it's much more than just a tool for writing manual pages, and I expect it to be useful to most --if not all-- C programmers. It is a command-line tool that finds C source code (for example, a function definition) in arbitrary projects. It doesn't use any indexing mechanism (unlike ctags and similar tools). This means that it can be used right after cloning some repository, without having to first generate an index.
