# Mimic the install_link function of texlinks

# Should have the same behavior as the one in /usr/bin/texlinks
# except that it is under the control of the package manager
# Note that $1 corresponds to $src and $2 to $dest in this function
# ( Arguments are switched because texlinks main function sends them switched )
# This function should not be called from an ebuild, prefer etexlinks that will
# also do the fmtutil file parsing.

# created. We cannot use texlinks with portage as it is not DESTDIR aware.

# the same dir as the source)
# Also, as this eclass must not depend on a tex distribution to be installed we
# cannot use texlinks from here.
