 Artistic Style is a source code indenter, formatter, and beautifier for the C,
-C++, C# and Java programming languages. It automatically re-indents and
+C++, C++/CLI, Objective-C, C# and Java programming languages.
-re-formats source files and can be used from a command line.
+
+When indenting source code, we as programmers have a tendency to use both spaces
+and tab characters to create the wanted indentation. Moreover, some editors by
+default insert spaces instead of tabs when pressing the tab key. Other editors
+(Emacs for example) have the ability to "pretty up" lines by automatically
+setting up the white space before the code on the line, possibly inserting
+spaces in code that up to now used only tabs for indentation.
+
+The NUMBER of spaces for each tab character in the source code can change
+between editors (unless the user sets up the number to his liking...). One of
+the standard problems programmers face when moving from one editor to another is
+that code containing both spaces and tabs, which was perfectly indented,
+suddenly becomes a mess to look at. Even if you as a programmer take care to
+ONLY use spaces or tabs, looking at other people's source code can still be
+problematic.
+
+To address this problem, Artistic Style was created -- a filter written in C++
+that automatically re-indents and re-formats C / C++ / Objective-C / C++/CLI / C#
+/ Java source files. It can be used from a command line, or it can be
+incorporated as a library in another program.
