How to set up etags with emacs

1. Create tags table:
1. Navigate to the source code directory
2. Run the command find . -name "*.[chCH]" -print | etags - (assuming that etags is already installed). This will create a TAGS file in the directory from which the aforementioned command is run
3. In emacs do M-x visit-tags-table and navigate to the directory where the aforementioned command was run. This will load the TAGS table
