-This file is an extension of the package pict2e.sty which extends the standard
-picture LaTeX environment according to what Leslie Lamport specified in the
-second edition of his LaTeX manual.
 
-This further extension allows to draw lines and vectors with any non integer
-slope parameters, to draw dashed lined of any slope, to draw arcs and curved
-vectors, to draw curves where just the interpolating nodes are specified
-together with the slopes at the nodes; closed paths of any shape can be filled
-with color; all coordinates are treated as ordered pairs, i.e. 'complex numbers'.
-Some of these features have been incorporated in the 2011 version of pict2e;
-therefore this package avoids any modification to the original pict2e commands.
+The package bundle curve2e is composed of the following files
 
-Curve2e now accepts polar coordinates in addition to the usual cartesian ones;
-several macros have been upgraded and a new macro for tracing cubic Bezier
-splines with their control nodes specified in polar form is available.

+The -almost compatible- frase is necessary to explain that this version
+of curve2e uses some `functions' of the LaTeX3 language that were made
+available to the LaTeX developer by mid October 2018. 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.
