+GtkSourceView is a GNOME library that extends GtkTextView, the
+standard GTK+ widget for multiline text editing. GtkSourceView adds
+support for syntax highlighting, undo/redo, file loading and saving,
+search and replace, a completion system, printing, displaying line
+numbers, and other features typical of a source code editor.
+
+Features:
+  * Accurate syntax highlighting for most popular programming languages
+    (C, C++, Java, C#, Fortran, etc.), scripting languages (sh, Python,
+    Perl, Ruby, PHP, TCL, etc.), markup languages (XML, HTML, DocBook,
+    LaTeX, etc.) and many others
+  * Customizable visual style using style schemes
+  * Unlimited Undo/Redo
+  * File loading and saving
+  * Extensible completion framework
+  * Search and replace, with regex support
+  * Line numbers
+  * Line marks (useful for bookmarks, breakpoints, etc.)
+  * Printing through easy integration with the GtkPrintOperation API
+  * Highlight the current line
+  * Highlight the matching bracket
+  * Right margin
+  * Represent whitespace characters with symbols
+  * A minimap, which shows an overview of the text
+  * Extended keyboard navigation (smart Home/End, smart backspace,
+    auto indentation, line moving, etc.)
+  * Can be used from many programming languages. Thanks to GObject
+    Introspection, automatic bindings are available for JavaScript,
+    Python, Vala and others. For C++, there is gtksourceviewmm
+
+If you would like to build the HTML documentation, pass DOCS=true
+to the build script. This introduces dependencies on gi-docgen and
+python-toml.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
