Example
ctags is a useful utility you can use to read and move around the source code more efficiently. The built-in ctags(1) however is not the Exuberant Ctags utility you might expect.
You can install Exuberant Ctags (exctags(1)) using either ports or pkg:
Build exctags(1) using ports
cd /usr/ports/devel/ctags/ && make install clean
Download and install a prebuilt binary of Exuberant Ctags:
pkg install ctags
Create the tag file
exctags -R
