The flags currently used by xrmap come for a large part from the SVG flags
of the openclipart collection
    http://www.openclipart.org
with some minor modifications and replacements.

They have been completed so as to include all data needed by xrmap, e.g. 
all US and Canadian State flags, and all other American, Australian, 
British, Canadian, Danish and French dependencies and territories -
in total about 50 additional flags.

These additional SVG flags have either been compiled from public domain 
sources, or obtained by various other tools (noticeably 'potrace',
used to convert bitmap flags into vector format, see e.g. usa_florida.svg
which was obtained in this way). We release them in the public domain
(unless this would contradict the original license, but we are unaware of
any such case).
    
The 'buildflags' main use is to process the collection of  source SVG flags 
and convert them into other formats. This requires inkscape version >= 0.42
