Manage your PATH with a nice, one-directory-per-line file, rather than a gargantuan blob of colon-delimited text. https://gist.github.com/willurd/5648907

	# Read the contents of ~/.path into $PATH, if ~/.path exists. ~/.path should be a file
	# consisting of one path on each line, such as:
	#
	# ~$ cat ~/.path
	# # vim: ft=sh
	# ~/usr/bin
	# /opt/local/bin
	# ... etc ...
	#
	# Note that comments begin with a hash (#).
