+"""Compile an EA from .mq5 to .ex5 with MetaEditor (doc 07 §1).
+
+The tester runs a compiled ``.ex5``. Compile from the command line so the
+bridge can do it programmatically. Custom indicators the EA calls must be
+compiled too and placed in ``MQL5\\Indicators\\``. If the EA's ``#include``
+files live in a non-standard folder, compile the terminal in portable mode
+(``/portable``) so MetaEditor resolves includes from that terminal's
+``MQL5\\Include\\``.
