aspline(1) interpolates an Akima-spline through a series of given points. The Akima-spline interpolation approximates a manually drawn curve better than the ordinary splines, but the second derivative is not continuous. The Akima-spline algorithm is described in "A New Method of Interpolation and Smooth Curve Fitting Based on Local Procedures", H. Akima, J. Assoc. Comput. Mach., 17(4), 1970, pp. 589-602. doi:10.1145/321607.321609

    2010-04-27 - Stuart Prescott <stuart+debian@nanonanonano.net> spline (1.2-1) unstable; urgency=low * New upstream release, fixing bugs in existing package: - crash with long comment lines. - duplication of output lines due to unwanted compiler optimisation (Closes: #578004). (thanks to David Frey for his assistance in tracking down these bugs) * New maintainer, thanks to David Frey for his previous work (Closes: #527149). * Change from native to non-native package. * Patch Makefile to not have arch-specific directives. * Add a rudimentary test suite so that a reoccurence of #578004 on any arch will cause a FTBFS. * Add Homepage field. * Update package description to include citation to algorithm. * Update debian/copyright. * Change packaging to debhelper + 3.0 (quilt). * Drop unneeded prerm script. * Bump Standards Version to 3.8.4. (No changes needed).
