+BXeepic Package
+===============
+
+LaTeX: Reimplementation of epic/eepic features using pict2e engine
+
+The eepic package (authored by Conrad Kwok) is one of packages to
+provide small-size extention to the picture environment of LaTeX
+(and epic package) and employs the tpic drawing feature of DVI-wares.
+Back in 1990--2000 the use of epic + eepic was widespread because
+many of the legacy DVI-wares (dvips, dvipdfmx, etc.) support tpic
+(and thus eepic extension). But pdfTeX engine has never supported
+tpic. As consequence, the use of epic + eepic was gradually replaced
+by pict2e as pdfTeX became more popular.
+
+In most cases drawings using epic + eepic are easily converted to
+pict2e ones, but there are features that eepic supports but pict2e
+does not --- e.g. ellipsis, dashed line. The present package provides
+almost full features of epic + eepic implemented on pict2e engines.
+Thus one can make epic + eepic drawings work on pdfTeX; moreover,
+one can use eepic and pict2e in the same document.
+
+### Installation
+
+  - `*.sty`, `*.def` → $TEXMF/tex/latex/bxeepic
+
+### Usage
+
+Load this package after loading pict2e.
+
+    \usepackage[<pict2e options>]{pict2e}
+    \usepackage{bxeepic}
+
+If pict2e is not yet loaded in loading bxeepic then it is loaded
+automatically, and in this case every option given to bxeepic will
+be passed to pict2e.
+
+    \usepackage[<pict2e options>]{bxeepic}
+
+This package provides all commands of epic and eepic packages, except
+the following:
+
+  - Shading: `\blacken`, `\whiten`, `\shade`, `\texture`, `\filltype`
+  - Dashed line with dotted dashes: the second optional argument of
+    `\dashline` is ignored.
+  - Dotted line with user-defined dots: the optional argument of
+    `\dottedline` is ignored.
+
+### Notice
+
+  - When behavior of a command differs btween eepic and epic, then
+    that of eepic is adopted.
+  - When behavior of a command differs btween pict2e and eepic, then
+    that of pict2e is adopted.
+  - However, `\arc` command can be used either in pict2e or eepic
+    syntax; when it looks like `\arc{...}{...}{...}` then eepic syntax
+    is assumed.
+  - When bxeepic is loaded, both epic and eepic packages are marked
+    as ‘already-loaded’; so one can load bxeepic earlily and then
+    the packages that rely on epic and eepic will work happily.
+
+Revision History
+----------------
+
+  * Version 0.2 <2013/04/28>
+      - The bxdpxp2e module, which provides proper support for
+        dvipdfmx, was abolished because the recent pic2e (>=v0.2y)
+        has the support.
+      - Documentation.
+  * Version 0.1 <2010/08/08>
+      - The first public version.

+% Note: After scaling by 180/pi, degree values are rounded to multiples
+% of 2^(-10). This rounding eliminates errors in the case of 'common
+% angles' such as 15deg, while generally it enlarges the maximum possible
+% error by factor about two.
