"""Build the single-file MQL5 Market versions and compile them on a testing install.

usage: build_market.py
  market/Tick_Forge.mq5            Expert (the utility product), TF_Gui / TF_Engine / TF_Expr inlined
  market/Tick_Forge_Indicator.mq5  indicator build of the same window (alternate)
Each is compiled; errors / warnings are printed. The Market compiles the uploaded source server-side, so it
must be ONE file with no custom includes (standard library includes are fine).
Set TF_DATA / TF_EDITOR for your own install.
