# calldbus de-complicates calling functions over D-Bus
# It is useful for testing Filer's D-Bus interface, e.g., from the command line
# like this:
#   calldbus org.freedesktop.FileManager1 ShowFolders /home/user /home/user/Documents
#   calldbus org.freedesktop.FileManager1 ShowItems /home/user /home/user/Documents/file.txt
#   calldbus org.freedesktop.FileManager1 ShowItemProperties /home/user/file.txt
#   calldbus org.freedesktop.FileManager1 SortOrderForUrl /home/user
