 # XML output generator for Open Fortran Parser
 
 This is an extension of Open Fortran Parser (OFP), which outputs abstract syntaxt tree (AST)
-in XML format - to a file or to 'System.out'.
+in XML format of parsed Fortran file - to a file or to `System.out`.
 
 
 ## dependencies
 
   - Open Fortran Parser 0.8.4-1
 
-  https://github.com/mbdevpl/open-fortran-parser/releases/tag/v0.8.4-1
+    https://github.com/mbdevpl/open-fortran-parser/releases/tag/v0.8.4-1
 
-  This is a patched version of OFP. Specifically, 'FortranParserActionPrint' class in OFP
-  could not be properly subclassed due to access levels of members of that class, so for example
-  writing my own printer would introduce a lot of code duplication. Patch resolves this,
-  without affecting any functionality of the Parser.

+## how to build
+
+Put dependencies in `lib` directory, and run:
+
+```
+ant
+```
+
+This will create a `.jar` file in `dist` directory.
 
 ## how to run
 
+```bash
+java -cp "/path/to/dependencies/*" fortran.ofp.FrontEnd --class fortran.ofp.XMLPrinter \
+  --output output.xml --verbosity 0~100 input.f
+```
+
+where:
+
+  - The `--verbosity` flag controls verbosity of the parse tree. Defaluts to `100` when omitted.
+
+      * Maximum, `100`, means that all details picked up by Open Fortran Parser will be preserved.
+
+      * Minimum, `0`, means that tree will contain only what is needed to reconstruct the program
+        without changing it's meaning.
+
+  - The `--output` flag controls where the XML should be written. Defaults to standard output
+    when omitted.
+
+... and remaining command-line options are exactly as defined in OFP 0.8.4.
+
+To parse `some_fortran_file.f` and save XML output in `tree.xml` with minimum verbosity:
+
+```bash
+java -cp "./lib/*:./dist/*" fortran.ofp.FrontEnd --class fortran.ofp.XMLPrinter \
+  --output tree.xml --verbosity 0 some_fortran_file.f
+```
+
+And to dump XML with maximum verbosity to console:
+
+```bash
+java -cp "./lib/*:./dist/*" fortran.ofp.FrontEnd --class fortran.ofp.XMLPrinter \
+  --verbosity 100 some_fortran_file.f
+```
+
