+# All text after a double hash (##) is considered a comment and is placed in
+# front of the TAG it is preceding.
+#
+# All text after a single hash (#) is considered a comment and will be ignored.
+# The format is:
+# TAG = value [value, ...]
+# For lists, items can also be appended using:
+# TAG += value [value, ...]
+# Values that contain spaces should be placed between quotes (\" \").
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all text
+# before the first occurrence of this tag. Doxygen uses libiconv (or the iconv
+# built into libc) for the transcoding. See http://www.gnu.org/software/libiconv
+# for the list of possible encodings.
+# The default value is: UTF-8.
+

+
+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded by
+# double-quotes, unless you are using Doxywizard) that should identify the

+# Debug CLI {{'{#'}}clicmd}
+
+The VPP network stack comes equipped with a set of commands that are useful
+for debugging.
+
+The easiest way to access the CLI (with proper permissions) is to use the
+vppctl command:
+
+```
+sudo vppctl <cli-command>
+```
+
+The CLI parser matches static keyword strings, eventually invoking an action
+function. Unambiguous partial keyword matching always occurs. The action
+functions consume input until satisfied or until they fail. This model makes
+for easy coding, but does not guarantee useful "help" output. It's up to the
+CLI command writer to add useful help strings.
+
+You can find the source code of CLI commands by searching for instances of the
+@c VLIB_CLI_COMMAND macro in the code source files.
+
+Please help maintain and improve this document to make and keep these commands
+clear and useful!
+
+@todo Document where to modify this CLI intro text.
+
+
+## Debug and Telnet CLI
+
+The debug CLI is enabled with the unix interactive parameter or startup
+configuration option. This causes VPP to start without daemonizing and
+presents a command line interface on the terminal where it is run.
+
+The Telnet CLI is enabled with the `cli-listen localhost:5002` option which
+will cause VPP to listen for TCP connections on the localhost address port
+@c 5002. A Telnet client can then connect to this port (for example, `telnet
+localhost 5002`) and will receive a command line prompt.
+
+This configuration will enable both mechanisms:
+
+```
+unix {
+ interactive
+ cli-listen localhost:5002
+}
+```
+
+The debug CLI can operate in line mode, which may be useful when running
+inside an IDE like Emacs. This is enabled with the option
+`unix cli-line-mode`. Several other options exist that alter how this
+CLI works, see the @ref syscfg section for details.
+
+The CLI starts with a banner graphic (which can be disabled) and a prompt. The
+prompt will typically read `vpp` for a release version of VPP and `DBGvpp#`
+for a development version with debugging enabled, for example:
+
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ vpp#
+
+versus:
+
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ DBGvpp#
+
+This prompt can be configured with the `unix cli-prompt` setting and the
+banner is disabled with `unix cli-no-banner`.
+
+## CLI features
+
+The CLI has several editing features that make it easy to use.
+
+- Cursor keys left/right will move the cursor within a command line;
+ typing will insert at the cursor; erase will erase at the cursor.
+
+- Ctrl-left/right will search for the start of the next word to
+ the left or right.
+- Home/end will jump the cursor to the start and end of the line.
+- Cursor keys up/down and ^P/^N iterate through the command history
+ buffer. Lines from the history buffer may be edited. New commands
+ are added to the end of the buffer when executed; though
+ duplicates of the previous command are not added.
+- ^U erases the line contents from the left of the cursor to the
+ start.
+- ^K erases the contents from the cursor to the end.
+- ^S/^R will search the command history forwards or in reverse for
+ a command; start typing for matches to auto complete.
+- ^L will clear the screen (if supported by the terminal) and repaint
+ the prompt and any current line. The cursor position is also
+ retained.
+- The CLI can be closed with the quit command. Alternatively, ^D on
+ an empty input line will also close the session. Closing the debug
+ session will also shutdown VPP.
+
+Output that exceeds the length of a terminal page will be buffered, up to a
+limit.
+
+- Space or page-down displays the next page.
+- Enter or down-arrow displays the next line.
+- Page-up goes back a page.
+- Up-arrow goes up a line.
+- Home/end jump to the start/end of the buffered output.
+- The key q quits the pager. Space and enter will also quit the
+ pager if the end of the buffer has been reached.

+# Startup Configuration {{'{#'}}syscfg}
+
+The VPP network stack comes with several configuration options that can be
+provided either on the command line or in a configuration file.
+
+Specific applications built on the stack have been known to require a dozen
+arguments, depending on requirements. This section describes commonly-used
+options and parameters.
+
+You can find command-line argument parsers in the source code by searching for
+instances of the `VLIB_CONFIG_FUNCTION` macro. The invocation
+`VLIB_CONFIG_FUNCTION(foo_config, "foo")` will cause the function
+`foo_config` to receive all the options and values supplied in a parameter
+block named "`foo`", for example: `foo { arg1 arg2 arg3 ... }`.
+
+@todo Tell the nice people where this document lives so that the might
+help improve it!
+
+## Command-line arguments
+
+Parameters are grouped by a section name. When providing more than one
+parameter to a section all parameters for that section must be wrapped in
+curly braces.
+
+```
+/usr/bin/vpp unix { interactive cli-listen 127.0.0.1:5002 }
+```
+
+Which will produce output similar to this:
+
+ <startup diagnostic messages>
+ _______ _ _ _____ ___
+ __/ __/ _ \ (_)__ | | / / _ \/ _ \
+ _/ _// // / / / _ \ | |/ / ___/ ___/
+ /_/ /____(_)_/\___/ |___/_/ /_/
+
+ vpp# <start-typing>
+
+When providing only one such parameter the braces are optional. For example,
+the following command argument, `unix interactive` does not have braces:
+
+```
+/usr/bin/vpp unix interactive
+```
+
+The command line can be presented as a single string or as several; anything
+given on the command line is concatenated with spaces into a single string
+before parsing.
+
+VPP applications must be able to locate their own executable images. The
+simplest way to ensure this will work is to invoke a VPP application by giving
+its absolute path; for example: `/usr/bin/vpp <options>`. At startup, VPP
+applications parse through their own ELF-sections (primarily) to make lists
+of init, configuration, and exit handlers.
+
+When developing with VPP, in _gdb_ it's often sufficient to start an application
+like this at the `(gdb)` prompt:
+
+```
+run unix interactive
+```
+
+## Configuration file
+
+It is also possible to supply parameters in a startup configuration file the
+path of which is provided to the VPP application on its command line.
+
+The format of the configuration file is a simple text file with the same
+content as the command line but with the benefit of being able to use newlines
+to make the content easier to read. For example:
+
+```
+unix {
+ nodaemon
+ log /tmp/vpp.log
+ full-coredump
+ cli-listen localhost:5002
+}
+api-trace {
+ on
+}
+dpdk {
+ dev 0000:03:00.0
+}
+```
+
+VPP is then instructed to load this file with the `-c` option:
+
+```
+/usr/bin/vpp -c /etc/vpp/startup.conf
+```
+
