examples: sort them per language and complete them
Convert some of the READMEs to Markdown, which is now more common, and nicely displayed in some git hosting services. Add missing READMEs and Makefiles. Generate XML, HTML and Dot files. Be sure to ship the test files. Complete CLEANFILES to remove all generated files. * examples/calc++: Move into... * examples/c++: here. * examples/mfcalc, examples/rpcalc: Move into... * examples/c: here. * examples/README.md, examples/c++/calc++/Makefile, examples/c/local.mk, * examples/c/mfcalc/Makefile, examples/c/rpcalc/Makefile, * examples/d/README.md, examples/java/README.md: New files. * examples/test (medir): Be robust to deeper directory nesting.

This directory contains examples of Bison grammar files.
|

|
||||
Most of them come from the documentation, which should be installed together
|
||||
with Bison. The URLs are provided for convenience.

# rpcalc - Reverse Polish Notation Calculator
|
||||
The first example is that of a simple double-precision Reverse Polish
|
||||
Notation calculator (a calculator using postfix operators). This example
|
||||
provides a good starting point, since operator precedence is not an issue.
|
||||
|
||||
Extracted from the documentation: "Reverse Polish Notation Calculator"
|
||||
https://www.gnu.org/software/bison/manual/html_node/RPN-Calc.html
|
||||
|
||||
# mfcalc - Multi-Function Calculator
|
||||
A more complete C example: a multi-function calculator.
|
||||
|
||||
Extracted from the documentation: "Multi-Function Calculator: mfcalc".
|
||||
