# Put the desktop entry and the application icon where a desktop will find
# them, for a build made from this checkout.
#
# This is for somebody running from source. The `.deb` installs the same two
# files under `/usr` and needs none of this; `packaging/debian/build-deb.sh`
# is that path.
#
# **There is no media type here, and that is the difference from the rest of
# the family.** Slipcase Desktop and Slipcase Open open a document, so they
# associate themselves with `.slpc` and depend on `slipcase-common` to declare
# the type once for every product that reads it. Filebase opens a *folder*: it
# is handed a directory and asks it a question, and there is no file extension
# in that. So nothing here declares a type, nothing registers a handler, and
# this package depends on no other.
#
# The entry does declare `inode/directory`, which is what puts Filebase in a
# file manager's "Open With" for a folder. That is the same path the binary's
# one positional argument serves, and it is the only reason the argument
# exists.
