See + ginac/flags.h and ginac/matrix.h. * The Dilogarithm (Li2) now has floating point evaluation, derivative and a proper series expansion. * Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E). +* Some minor bugfixes, one major lsolve()-bugfix and documentation updates. 0.6.2 (21 June 2000) * ginaccint.bin is now launched by a binary program instead of by a scripts.
