+# GhostScript bundling
+# --------------------
+# Run build_windows.bat (or prepare_ghostscript.bat) BEFORE pyinstaller.
+# That script copies the following directories from the system
+# GhostScript installation into conf\ghostscript\:
+#
+#   conf\ghostscript\bin\   <- gswin64c.exe + gsdll64.dll
+#   conf\ghostscript\lib\   <- all .ps init files
+#
+# This spec detects those directories automatically and adds them to the
+# bundle under ghostscript\bin\ and ghostscript\lib\ inside _MEIPASS so
+# that print_label.py can find and launch the bundled executable.
+# If the directories are absent the build still succeeds (prints will fall
+# back to SumatraPDF on the target machine).
