+Command-Line Usage: CodeChecker and scan-build
+===============================================
+
+This document provides guidelines for running Clang Static Analyzer from the command line on whole projects.
+CodeChecker and scan-build are two CLI tools for using CSA on multiple files (tranlation units).
+Both provide a way of driving the analyzer, detecting compilation flags, and generating reports.
+CodeChecker is more actively maintained, provides heuristics for working with multiple versions of popular compilers and it also comes with a web-based GUI for viewing, filtering, categorizing and suppressing the results.
+Therefore CodeChecker is recommended in case you need any of the above features or just more customizability in general.
+
+Comparison of CodeChecker and scan-build
+----------------------------------------
+
+Static Analyzer is by design a GUI tool originally intended to be consumed by the XCode IDE.
+Its purpose is to find buggy execution paths in the program, and such paths are very hard to comprehend by looking at a non-interactive standard output.
+It is possible, however, to invoke the Static Analyzer from the command line in order to obtain analysis results, and then later view them interactively in a graphical interface.
+The following tools are used commonly to run the analyzer from the commandline.
+Both tools are wrapper scripts to drive the analysis and the underlying invocations of the Clang compiler:
+
+1. CodeChecker_ is a driver and web server that runs the Static Analyzer on your projects on demand and maintains a database of issues.

I'm not sure if the intent was to make the whole line italic, but that is the outcome.
