# Introduction

Several {{usecase}}s of {{uranie}} are described in this chapter with a small description of the 
implemented methods in the {{uranie}} platform. These macros are located in the sub-directory 
*"/share/uranie/macros"* of the installation folder of {{uranie}} (*\$URANIESYS*).

In this chapter, inside each macro, the {{uranie}} specific **namespaces** might not always be 
specified anymore. These specifications are gathered in the {{sentence2[language]}} file, introduced 
in [](#overview_root_namespace), which is automatically loaded when executing {{sentence1[language]}}. 
An example would be: 

{{
    "```{literalinclude} " + parent_dir
    + "/roottest/uranie/doc/overview/use_cases/" + language + "/rootlogon." + extension
    + "\n"
    + ":language: " + language + "\n"
    + "```"
}}
