For years I've avoided using emacs' tags table functions, but I finally had to break down and read about them tonight to search eficiently through a huge collection of Mathematica packages and applications.
After reading the fine manual it was easy to create a tags table of Mathematica function definitions and variable assignments:
cd topdir; find . -name "*.m" -print | grep -v BrowserCategories.m | \ etags \ --language=none \ --regex='/\([A-Za-z0-9$]+\)[ \t]*=/\1/' \ --regex='/\([A-Za-z0-9$]+\).*:=/\1/' -
The second regexp choked on a particular BrowserCategories.m; since they don't contain the definitions I'm looking for I removed them from consideration.
The two regexs find these sorts of things:
fact[1] = 1; fact[n_] := n fact[n - 1]
