Geeqie is an image viewer.
This script will download, compile, and install Geeqie on Debian-based systems.
If run from a folder that already contains the Geeqie sources, the source
code will be updated from the repository.
Dialogs allow the user to install additional features, including
additional pixbuf loaders.

Command line options are:
-v --version The version of this file
-h --help Output this text
-c --commit Checkout and compile commit ident
-t --tag Checkout and compile tag (e.g. v1.4 or v1.3)
