RUNNING IT
  Double-click TrussAnalyzer.exe. No installation is needed, and it runs
  from any folder, including a USB stick.
  Requires Windows 10 or 11 (64-bit). It uses the Microsoft Edge WebView2
  Runtime, which is already part of Windows 10/11. If it is missing,
  the program says so; install the free "Evergreen WebView2 Runtime"
  from Microsoft and start the program again.

  The first time, Windows SmartScreen may say "Windows protected your PC"
  because the program is new and not code-signed. Click "More info" and
  then "Run anyway".

WHAT IT DOES
  Truss model ............ enter joints (Easting, Northing), members,
                           supports and loads; member forces and
                           reactions are solved as you type and drawn.
  Northing-Easting method  the Northing-Easting Method of Truss Analysis,
                           worked joint by joint, step by step.
  Stiffness method ....... direct stiffness working: member [k], global [K],
                           supports, displacements, forces, reactions.
  Joint calculator ....... the original "Analysis of Member Forces" sheet.
  User manual ............ rules and sign convention.

  Bearings are measured clockwise from North; North and East are positive;
  tension is positive, compression negative. Units: kN and metres.
  Determinate trusses are solved by equilibrium; indeterminate ones by the
  stiffness method, using each member's EA.

FILES
  New / Open / Save / Save as  (Ctrl+N, Ctrl+O, Ctrl+S, Ctrl+Shift+S)
      Projects are saved as .truss files. You can also drag a .truss file
      onto TrussAnalyzer.exe to open it.
  Print / Save as PDF  (Ctrl+P)
      Prints the tab you are on. Choose "Save as PDF" as the printer
      to make a PDF report.
  Your last session is remembered automatically in
      %APPDATA%\TrussAnalyzer\state.json

REBUILDING FROM SOURCE (for developers; see the source zip)
  Needs Go 1.22 or newer.  From the source folder:
      python build_html.py truss-analyzer.html app.html
      set GOOS=windows& set GOARCH=amd64& set CGO_ENABLED=0
      go build -trimpath -ldflags "-H windowsgui -s -w" -o TrussAnalyzer.exe .
  rsrc_windows_amd64.syso holds the icon, version information and
  manifest (regenerate with tools/winresgen).
