+# This wrapper script is invoked by xdg-desktop-portal-termfilechooser.
+#
+# Inputs:
+# 1. "1" if multiple files can be chosen, "0" otherwise.
+# 2. "1" if a directory should be chosen, "0" otherwise.
+# 3. "0" if opening files was requested, "1" if writing to a file was
+#    requested. For example, when uploading files in Firefox, this will be "0".
+#    When saving a web page in Firefox, this will be "1".
+# 4. If writing to a file, this is recommended path provided by the caller. For
+#    example, when saving a web page in Firefox, this will be the recommended
+#    path Firefox provided, such as "~/Downloads/webpage_title.html".
+#    Note that if the path already exists, we keep appending "_" to it until we
+#    get a path that does not exist.
+# 5. The output path, to which results should be written.
+#
+# Output:
+# The script should print the selected paths to the output path (argument #5),
+# one path per line.
+# If nothing is printed, then the operation is assumed to have been canceled.
