PHP RTF Tools: Parse and generate RTF documents using templates

This package can parse and generate RTF documents using templates.

Currently it provides different classes that can:

- Process RTF documents from files or strings (RtfDocument class)
- Rewrite RTF documents splitting their tags into multiple lines so it can be easy to compare and find differences between two files using diff like utilities (RtfBeautifier)
- Extract raw text from RTF documents with some basic formatting capabilities (RtfBeautifier)
- Process RTF document templates with a macro language that suppports:

* Inline variables expansion within the document (variables are supplied by the caller)
* Expressions evaluation and replacement using PHP syntax (for example : date ( 'Y-m-d H:i:s' ))
* IF/ELSEIF/ELSE/ENDIF constructs, to conditionally include text in the output document
* REPEAT/FOR loops that can repeat blocks of text
* FOREACH loops that operate on array values supplied by the caller
(RtfTemplater class)

- Merge several RTF documents together including using the template processing objects, external files or strings, preserving details like fonts, colors, styles and avoiding page number repetition (RtfMerger class)
- A generic Rtf parser class is also provided, that can be used if you need more advanced capabilities when interpreting Rtf document contents (RtfParser class).

All the classes in this package have been designed to be able to process Rtf documents that may be larger than the available memory. This is useful when you need to handle at once several Rtf documents whose total size may exceed your current PHP memory limit.
