title

string examples.exp.ast_translate.title

Initial value:

=  '''This example will demonstrate how to use the AST
for matched result translations. ApgExp will be used to match
floating point numbers and the AST will be used to put the
numbers in a "normalized" form.
A second example will use the same AST to create a replacement
function to do replacements with the translated matches.
See also the examples/exp/ast.py and examples/exp/replace.py examples.
