open than with many editors: Scintilla lets you use proportional
fonts, bold and italics, multiple foreground and background colours,

Environment (IDE) that only has a few dependencies on other packages and is as
independent as possible from special desktop environments like KDE or GNOME.

The basic features of Geany are:
@itemize
@item syntax highlighting
@item code completion
@item auto completion of often constructed constructs like if, for and while
@item auto completion of XML and HTML tags
@item call tips
@item folding
@item many supported filetypes like C, Java, PHP, HTML, Python, Perl, Pascal
@item symbol lists
@item embedded terminal emulation
@item extensibility through plugins
