Projectile is one of my favourite Emacs packages and I recommend it for everyone coding in Emacs . It sets up many things for you that you'll appreciate whatever language you're programming in.
One day, M-x projectile-regenerate-tags gave me this errors:
projectile-regenerate-tags: ctags: invalid option -- 'e'
Try `ctags --help' for a complete list of options.
Of course, everything was perfectly well laid out in the documention, I just had to install Exuberant ctags:
# apt-get install exuberant-ctags
After that, projectile-regenerate-tags and consequently
M-. (find-tag) and M-* (pop-tag-mark) worked
like a charm.
