+File README.txt for package curve2e
+ [2019-03-29 v.2.0.1 Extension package for pict2e]
+
+
+
+The package bundle curve2e is composed of the following files
+
+curve2e.dtx
+curve2e.pdf
+README.txt
+curve2e-v161.sty
+ltxdoc.cfg
+
+curve2e.dtx is the documented TeX source file of file curve2e.sty; you get
+both curve2e.sty and curve2e.pdf by running pdflatex on curve2e.dtx.
+The ltxdoc.cfg file customises the way the documentation file is typeset.
+This .cfg file is not subject to the LPPL licence.
+
+README.txt, this file, contains general information.
+
+Curve2e-v161.sty contains the previous version of the package; see below
+why the older version might become necessary for the end user.
+
+Curve2e.sty 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'; coordinates may be expressed also in polar form.
+Some of these features have been incorporated in the 2011 version of
+pict2e; therefore this package avoids any modification to the original
+pict2e commands.
+
+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 same applies to quadratic Bezier splines.
+
+This version solves a conflict with package eso-pic.
+
+This version of curve2e is almost fully compatible with pict2e dated
+2014/01/12 version 0.2z.
+
+If you specify
+
+\usepackage[<pict2e options>]{curve2e}
+
+the package pict2e is automatically invoked with the specified options.
+
+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.
