+# CMAKE_PARSE_ARGUMENTS(<prefix> <options> <one_value_keywords>
+# <multi_value_keywords> args...)
+#
+# CMAKE_PARSE_ARGUMENTS() is intended to be used in macros or functions
+# for parsing the arguments given to that macro or function.  It
+# processes the arguments and defines a set of variables which hold the
+# values of the respective options.
+#
+# The <options> argument contains all options for the respective macro,
+# i.e.  keywords which can be used when calling the macro without any
+# value following, like e.g.  the OPTIONAL keyword of the install()
+# command.
+#
+# The <one_value_keywords> argument contains all keywords for this macro
+# which are followed by one value, like e.g.  DESTINATION keyword of the
+# install() command.
+#
+# The <multi_value_keywords> argument contains all keywords for this
+# macro which can be followed by more than one value, like e.g.  the
+# TARGETS or FILES keywords of the install() command.
+#
+# When done, CMAKE_PARSE_ARGUMENTS() will have defined for each of the
+# keywords listed in <options>, <one_value_keywords> and
+# <multi_value_keywords> a variable composed of the given <prefix>
+# followed by "_" and the name of the respective keyword.  These
+# variables will then hold the respective value from the argument list.
+# For the <options> keywords this will be TRUE or FALSE.
+#
+# All remaining arguments are collected in a variable
+# <prefix>_UNPARSED_ARGUMENTS, this can be checked afterwards to see
+# whether your macro was called with unrecognized parameters.
+#
+# As an example here a my_install() macro, which takes similar arguments
+# as the real install() command:
+#
+# ::
+#
+#    function(MY_INSTALL)
+#      set(options OPTIONAL FAST)
+#      set(oneValueArgs DESTINATION RENAME)
+#      set(multiValueArgs TARGETS CONFIGURATIONS)
+#      cmake_parse_arguments(MY_INSTALL "${options}" "${oneValueArgs}"
+#                            "${multiValueArgs}" ${ARGN} )
+#      ...
+#
+#
+#
+# Assume my_install() has been called like this:
+#
+# ::
+#
+#    my_install(TARGETS foo bar DESTINATION bin OPTIONAL blub)
+#
+#
+#
+# After the cmake_parse_arguments() call the macro will have set the
+# following variables:
+#
+# ::
+#
+#    MY_INSTALL_OPTIONAL = TRUE
+#    MY_INSTALL_FAST = FALSE (this option was not used when calling my_install()
+#    MY_INSTALL_DESTINATION = "bin"
+#    MY_INSTALL_RENAME = "" (was not used)
+#    MY_INSTALL_TARGETS = "foo;bar"
+#    MY_INSTALL_CONFIGURATIONS = "" (was not used)
+#    MY_INSTALL_UNPARSED_ARGUMENTS = "blub" (no value expected after "OPTIONAL"
+#
+#
+#
+# You can then continue and process these variables.
+#
+# Keywords terminate lists of values, e.g.  if directly after a
+# one_value_keyword another recognized keyword follows, this is
+# interpreted as the beginning of the new option.  E.g.
+# my_install(TARGETS foo DESTINATION OPTIONAL) would result in
+# MY_INSTALL_DESTINATION set to "OPTIONAL", but MY_INSTALL_DESTINATION
+# would be empty and MY_INSTALL_OPTIONAL would be set to TRUE therefor.

+# FindPackageHandleStandardArgs
+# -----------------------------
+#
+#
+#
+# FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name> ...  )
+#
+# This function is intended to be used in FindXXX.cmake modules files.
+# It handles the REQUIRED, QUIET and version-related arguments to
+# find_package().  It also sets the <packagename>_FOUND variable.  The
+# package is considered found if all variables <var1>...  listed contain
+# valid results, e.g.  valid filepaths.
+#
+# There are two modes of this function.  The first argument in both
+# modes is the name of the Find-module where it is called (in original
+# casing).
+#
+# The first simple mode looks like this:
+#
+# ::
+#
+#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(<name>
+#       (DEFAULT_MSG|"Custom failure message") <var1>...<varN> )
+#
+# If the variables <var1> to <varN> are all valid, then
+# <UPPERCASED_NAME>_FOUND will be set to TRUE.  If DEFAULT_MSG is given
+# as second argument, then the function will generate itself useful
+# success and error messages.  You can also supply a custom error
+# message for the failure case.  This is not recommended.
+#
+# The second mode is more powerful and also supports version checking:
+#
+# ::
+#
+#     FIND_PACKAGE_HANDLE_STANDARD_ARGS(NAME
+#       [FOUND_VAR <resultVar>]
+#       [REQUIRED_VARS <var1>...<varN>]
+#       [VERSION_VAR   <versionvar>]
+#       [HANDLE_COMPONENTS]
+#       [CONFIG_MODE]
+#       [FAIL_MESSAGE "Custom failure message"] )
+#
+# In this mode, the name of the result-variable can be set either to
+# either <UPPERCASED_NAME>_FOUND or <OriginalCase_Name>_FOUND using the
+# FOUND_VAR option.  Other names for the result-variable are not
+# allowed.  So for a Find-module named FindFooBar.cmake, the two
+# possible names are FooBar_FOUND and FOOBAR_FOUND.  It is recommended
+# to use the original case version.  If the FOUND_VAR option is not
+# used, the default is <UPPERCASED_NAME>_FOUND.
+#
+# As in the simple mode, if <var1> through <varN> are all valid,
+# <packagename>_FOUND will be set to TRUE.  After REQUIRED_VARS the
+# variables which are required for this package are listed.  Following
+# VERSION_VAR the name of the variable can be specified which holds the
+# version of the package which has been found.  If this is done, this
+# version will be checked against the (potentially) specified required
+# version used in the find_package() call.  The EXACT keyword is also
+# handled.  The default messages include information about the required
+# version and the version which has been actually found, both if the
+# version is ok or not.  If the package supports components, use the
+# HANDLE_COMPONENTS option to enable handling them.  In this case,
+# find_package_handle_standard_args() will report which components have
+# been found and which are missing, and the <packagename>_FOUND variable
+# will be set to FALSE if any of the required components (i.e.  not the
+# ones listed after OPTIONAL_COMPONENTS) are missing.  Use the option
+# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a
+# find_package(...  NO_MODULE) call.  In this case VERSION_VAR will be
+# set to <NAME>_VERSION and the macro will automatically check whether
+# the Config module was found.  Via FAIL_MESSAGE a custom failure
+# message can be specified, if this is not used, the default message
+# will be displayed.
+#
+# Example for mode 1:
+#
+# ::
+#
+#     find_package_handle_standard_args(LibXml2  DEFAULT_MSG
+#       LIBXML2_LIBRARY LIBXML2_INCLUDE_DIR)
+#
+#
+#
+# LibXml2 is considered to be found, if both LIBXML2_LIBRARY and
+# LIBXML2_INCLUDE_DIR are valid.  Then also LIBXML2_FOUND is set to
+# TRUE.  If it is not found and REQUIRED was used, it fails with
+# FATAL_ERROR, independent whether QUIET was used or not.  If it is
+# found, success will be reported, including the content of <var1>.  On
+# repeated Cmake runs, the same message won't be printed again.
+#
+# Example for mode 2:
+#
+# ::
+#
+#     find_package_handle_standard_args(LibXslt
+#       FOUND_VAR LibXslt_FOUND
+#       REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS
+#       VERSION_VAR LibXslt_VERSION_STRING)
+#
+# In this case, LibXslt is considered to be found if the variable(s)
+# listed after REQUIRED_VAR are all valid, i.e.  LibXslt_LIBRARIES and
+# LibXslt_INCLUDE_DIRS in this case.  The result will then be stored in
+# LibXslt_FOUND .  Also the version of LibXslt will be checked by using
+# the version contained in LibXslt_VERSION_STRING.  Since no
+# FAIL_MESSAGE is given, the default messages will be printed.
+#
+# Another example for mode 2:
+#
+# ::
+#
+#     find_package(Automoc4 QUIET NO_MODULE HINTS /opt/automoc4)
+#     find_package_handle_standard_args(Automoc4  CONFIG_MODE)
+#
+# In this case, FindAutmoc4.cmake wraps a call to find_package(Automoc4
+# NO_MODULE) and adds an additional search directory for automoc4.  Here
+# the result will be stored in AUTOMOC4_FOUND.  The following
+# FIND_PACKAGE_HANDLE_STANDARD_ARGS() call produces a proper
+# success/error message.

+# ------------------

+#
+# FIND_PACKAGE_MESSAGE(<name> "message for user" "find result details")
+#
+# This macro is intended to be used in FindXXX.cmake modules files.  It
+# will print a message once for each unique find result.  This is useful
+# for telling the user where a package was found.  The first argument
+# specifies the name (XXX) of the package.  The second argument
+# specifies the message to display.  The third argument lists details
+# about the find result so that if they change the message will be
+# displayed again.  The macro also obeys the QUIET argument to the
+# find_package command.
+#
+# Example:
+#
+# ::
+#
+#   if(X11_FOUND)
+#     FIND_PACKAGE_MESSAGE(X11 "Found X11: ${X11_X11_LIB}"
+#       "[${X11_X11_LIB}][${X11_INCLUDE_DIR}]")

 ## Executables
 
-The go-ethereum project comes with several wrappers/executables found in the `cmd` directory.
+Go Expanse comes with several wrappers/executables found in
+[the `cmd` directory](https://github.com/expanse-project/go-expanse/tree/develop/cmd):
 
-| Command    | Description |
+* `gexp` Expanse CLI (expanse command line interface client)
-|:----------:|-------------|
+* `bootnode` runs a bootstrap node for the Discovery Protocol
-| **`geth`** | Our main Ethereum CLI client. It is the entry point into the Ethereum network (main-, test- or private net), capable of running as a full node (default) archive node (retaining all historical state) or a light node (retrieving data live). It can be used by other processes as an gateway into the Ethereum network via JSON RPC endpoints exposed on top of HTTP, WebSocket and/or IPC transports. Please see our [Command Line Options](https://github.com/ethereum/go-ethereum/wiki/Command-Line-Options) wiki page for details. |
+* `exptest` test tool which runs with the [tests](https://github.com/expanse-project/tests) suite:
-| `abigen` | Source code generator to convert Ethereum contract definitions into easy to use, compile-time type-safe Go packages. It operates on plain [Ethereum contract ABIs](https://github.com/ethereum/wiki/wiki/Ethereum-Contract-ABI) with expanded functionality if the contract bytecode is also available. However it also accepts Solidity source files, making development much more streamlined. Please see our [Native DApps](https://github.com/ethereum/go-ethereum/wiki/Native-DApps:-Go-bindings-to-Ethereum-contracts) wiki page for details. |
+  `/path/to/test.json > exptest --test BlockTests --stdin`.
-| `bootnode` | Stripped down version of our Ethereum client implementation that only takes part in the network node discovery protocol, but does not run any of the higher level application protocols. It can be used as a lightweight bootstrap node to aid in finding peers in private networks. |
+* `evm` is a generic Expanse Virtual Machine: `evm -code 60ff60ff -gas
-| `disasm` | Bytecode disassembler to convert EVM (Ethereum Virtual Machine) bytecode into more user friendly assembly-like opcodes (e.g. `echo "6001" | disasm`). For details on the individual opcodes, please see pages 22-30 of the [Ethereum Yellow Paper](http://gavwood.com/paper.pdf). |
+  10000 -price 0 -dump`. See `-h` for a detailed description.
-| `evm` | Developer utility version of the EVM (Ethereum Virtual Machine) that is capable of running bytecode snippets within a configurable environment and execution mode. Its purpose is to allow insolated, fine graned debugging of EVM opcodes (e.g. `evm --code 60ff60ff --debug`). |
+* `disasm` disassembles EVM code: `echo "6001" | disasm`
-| `gethrpctest` | Developer utility tool to support our [ethereum/rpc-test](https://github.com/ethereum/rpc-tests) test suite which validates baseline conformity to the [Ethereum JSON RPC](https://github.com/ethereum/wiki/wiki/JSON-RPC) specs. Please see the [test suite's readme](https://github.com/ethereum/rpc-tests/blob/master/README.md) for details. |
+* `rlpdump` prints RLP structures
-| `rlpdump` | Developer utility tool to convert binary RLP ([Recursive Length Prefix](https://github.com/ethereum/wiki/wiki/RLP)) dumps (data encoding used by the Ethereum protocol both network as well as consensus wise) to user friendlier hierarchical representation (e.g. `rlpdump --hex CE0183FFFFFFC4C304050583616263`). |
