+.It Fl f Ns Cm default-eraseable
+Force all expressions to be "eraseable" which permits the compiler to
+remove unused functions, variables and statements. This is equivlant to
+putting [[eraseable]] on all definitions. This is dangerous as it breaks
+auto cvars, definitions for functions the engine may be looking for and
+translatable strings. Instead, you can mark a definition with [[noerase]]
+to prevent this from happening.
