# openwrt-xburst/staging_dir/target-mipsel_uClibc-0.9.32/usr/lib/*oct*' if
# compilation fails for you.  Mostly that doesn't matter on clean rebuilds
# anyways.

define Package/octave/Default/description
GNU Octave is a high-level language, primarily intended for numerical
computations. It provides a convenient command line interface for solving
linear and nonlinear problems numerically, and for performing other numerical
experiments using a language that is mostly compatible with Matlab. It may
also be used as a batch-oriented language.
