+## `json`
+
+```lua
+local json = require "json"
+```
+
+Json encoder/decoder
+
+The following functions are exposed by the library:
+
+    decode(string): Decodes a JSON string. Returns nil and an error string if
+                    the string could not be decoded.
+    encode(value):  Encodes a value into a JSON string. Returns nil and an error
+                    string if the value could not be encoded.
+

+```lua
+local flag = require "flag"
+
+fs = flag.new()
+
+fs:string("name", "foo", "String help string")
+fs:intArg("title", 1, "Title")
+fs:numberArg("title", 1, "Title")
+
+flags = fs:parse(arg) -- arg is the remaining command line arguments
+assert(flags.title == 2, "expected title to be 2")
+assert(flags.title == 2.32, "expected title to be 2.32")
+```
+
+## `sh`
+
+```lua
+local sh = require "sh"
+```
+
+gluash is a interface to call any program as it were a function. Programs are executed asynchronously to enable streaming of data in pipes.
+
+In all discussions bellow the imported module will be referred to as `sh`.
+
+Commands are called just like functions, executed on the sh module.
+
+```lua
+sh.ls("/")
+```
+
+For commands that have exotic names, names that are reserved words, or to execute absolute or relative paths call the sh module directly.
+
+```lua
+sh("/bin/ls", "/")
+```
+
+#### Multiple Arguments
+Commands with multiple arguments have to be invoked with a separate string for each argument.
+
+```lua
+-- this works
+sh.ls("-la", "/")
+
+-- this does not work
+sh.ls("-la /")
+```
+
+#### Piping
+Piping in sh is done almost like piping in the shell. Just call next command as a method on the previous command.
+
+```lua
+sh.du("-sb"):sort("-rn"):print()
+```
+
+If the command has a exotic name, or a reserved word, call the command through `cmd(path, ...args)`. The first argument in `cmd` is the path.
+
+```lua
+sh.du("-sb"):cmd("sort", "-rn"):print()
+```
+
+### Waiting for Processes
+All commands are executed by default in the background, so one have to explicitly wait for a process to finish. There are several ways to wait for the command to finish.
+
+* `print()`     - write stdout and stderr to stdout.
+* `ok()`        - aborts execution if the command's exit code is not zero
+* `success()`   - returns true of the commands exit code is zero
+* `exitcode()`  - returns the exit code of the command
+
+### Abort by Default
+It is possible to set the module to abort on errors without checking. It can be practical in some occasions, however performance will be degraded. When global exit code checks are done the commands are run in series, even in pipes, and output is saved in memory buffers.
+
+To enable global exit code settings call the sh module with an table with the key `abort` set to true.
+
+```lua
+sh{abort=true}
+```
+
+To read current settings in the module call the module with an empty table.
+```lua
+configuration = sh{}
+print("abort:", configuration.abort)
+```
+
+### Analyzing Output
+There are several options to analyze the output of a command.
+
+#### lines()
+An iterator is accessible by calling the method `lines()` on the command.
+
+```lua
+for line in sh.cat("/etc/hosts"):lines() do
+  print(line)
+end
+```
+
+#### stdout([filename]), stderr([filename]), combinedOutput([filename])
+`stdout()`, `stderr()`, and `combinedOutput()` all returns the output of the command as a string. An optional `filename` can be given to the method, in that case the output is also written to the file. The file will be truncated.
+
+```lua
+-- print output of command
+output = sh.echo("hello world"):combinedOutput("/tmp/output")
+print(output)
+```
+
+In the example above will print `hello world` and it will write it to `/tmp/output`
+
+### Glob Expansion
+There is no glob expansion done on arguments, however there is a glob functionality in sh.
+
+```lua
+sh.ls(sh.glob("*.go"))
+```
+
+## `re`
+
+```lua
+local re = require "re"
+```
+
+Regular Expressions
+
+### API
+
+re.find , re.gsub, re.match, re.gmatch are available. These functions have the same API as Lua pattern match.
+gluare uses the Go regexp package, so you can use regular expressions that are supported in the Go regexp package.
+
+In addition, the following functions are defined:
+```
+gluare.quote(s string) -> string
+Arguments:
+
+s string:	a string value to escape meta characters
+
+Returns:
+
+string:	escaped string
+gluare.quote returns a string that quotes all regular expression metacharacters inside the given text.
+```
+
+## `simplebox`
+
+```lua
+local simplebox = require "simplebox"
+```
+
+Simple encryption
+
+### API
+
+#### Create a new instance of simplebox with a newly generated key
+
+```lua
+local simplebox = require "simplebox"
+local key = simplebox.genkey()
+print("key is: " .. key)
+local sb = simplebox.new()
+
+
+```
