DESCRIPTION="Library for cross-platform C file functions"

KEYWORDS="amd64 ~arm64 x86"
IUSE="nls unicode debug"

# This library has a circular build-time dependency on libuna. According to upstream, this is
# a non-issue as long as we use the pre-assembled download tarballs because they contain all
# required sources (see https://github.com/libyal/libuna/issues/7). In this case, we set a
# unilateral dependency libfile --> libuna and hope for the best. (Dependent packages should
# include both packages as dependency.)

#  --disable-shared-libs   disable shared library support
# not supported in the ebuild at the moment - kind of defeats the entire process

#  --enable-winapi         enable WINAPI support for cross-compilation
#                          [default=auto-detect]
# not supported in the ebuild at the moment - requires windows.h, does not make much sense for us
