rem Build a distributable pyflashgui: a PyInstaller one-directory build, checked,
rem then wrapped in a Windows installer with Inno Setup.
rem
rem   build.cmd            build, check, and make setup.exe
rem   build.cmd nosetup    stop after the checked one-directory build
rem   build.cmd setup      only make setup.exe, from the dist\pyflashgui already
rem                        there -- which CI has had signed in between
rem
rem The tests run first, unless WINDOWS_TESTS_PASSED is set to 1: that is CI
rem saying its Windows test job has already passed for this commit, which the
rem installer job waits for. Nothing on your own machine sets it.
rem
rem Two notes for editing this file: batch files must keep CRLF line endings or
rem cmd.exe mis-parses labels and goto (.gitattributes enforces it), and
rem "if errorlevel 1 goto :fail" is used rather than "|| goto :fail", which is
rem unreliable after a quoted interpreter invocation.
