-USAGE:
-  $FUNCNAME h[elp]
-    Print this help message (also done if command not found)
-  $FUNCNAME l[ist]
-    Print the current directories in PATH, one per line (default command)
-  $FUNCNAME i[nsert] DIR
-    Add a directory to the front of PATH, checking for existence and uniqueness
-  $FUNCNAME a[ppend] DIR
-    Add a directory to the end of PATH, checking for existence and uniqueness
-  $FUNCNAME r[emove] DIR
-    Remove all instances of a directory from PATH
-
-INTERNALS:
-  $FUNCNAME s[et] [DIR1 [DIR2...]]
-    Set the PATH to the given directories without checking existence or uniqueness
-  $FUNCNAME c[heck] DIR
-    Return whether DIR is a component of PATH
