\section{Description}

\Prog{Fex} is a bioacoustic analysis tool for calculating the frequency
excursion of an audio recording of bird songs or other sound waves.

\section{Fex-gtk}

\Prog{Fex-gtk} is a wrapper script for fex that facilitates batch
processing of large numbers of wave files.  \Prog{Fex-gtk} can be
provided a list of file names, or can be run with no parameters to
provide a dialog window to select input wave files.  \Prog{Fex} will be
run on each input file, and the results can either be stored to a data
file or displayed in a dialog window upon completion.

\Prog{Fex-gtk} is also the executable target of \File{fex.desktop} to
allow for drag-and-drop operation of \Prog{fex}.  The desktop file can
accept any number of wave files as a drop target.














\section{Configuration}
\Prog{Fex} is configured via a runtime configuration file read from one
of
\File{\$XDG\_CONFIG\_HOME/fex/config},
\File{\$HOME/.config/fex/config},
\File{\$HOME/.fexrc}, or
