Should the user +have an older or a basic/incomplete installation of the TeX system, +such L3 functions might not be available. This is why this +package checks the presence of the developer interface; in case +such interface is not available it falls back to the previous version +renamed curve2e-v161.sty, which is part of this bundle, and that must +not be renamed in any way. The compatibility mentioned above implies +that the user macros remain the same, but their implementation requires +the L3 interface. + +The package has the LPPL status of author maintained. + +According to the LPPL licence, you are entitled to modify this package, +as long as you fulfil the few conditions set forth by the Licence. + +Nevertheless this package is an extension to the standard LaTeX package +pict2e (2014). Therefore any change must be controlled on the +parent package pict2e, so as to avoid redefining what has already been +incorporated in the official package. + +If you prefer sending me your modifications, as long as I will maintain +this package, I will possibly include every (documented) suggestion or +modification into this package and, of course, I will acknowledge your +contribution. + +Claudio Beccari + +claudio dot beccari at gmail dot com + %% %% %% Distributable under the LaTeX Project Public License, |
