Artistic Style is a source code indenter, formatter, and beautifier for the C,
C++, C++/CLI, Objective-C, C# and Java programming languages.

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.
