GTK app for viewing and cleaning metadata in files

 Metadata within a file can tell a lot about you. Cameras record data about when
 a picture was taken and what camera was used. Office applications automatically
 add author and company information to documents and spreadsheets. Maybe you
 do not want to disclose those information.
 .
 This tool allows you to view metadata in your files and to get rid of them as
 much as possible.
 .
 Under the hood, it relies on mat2 to parse and remove the metadata.
