<Overload retVal="void" descr="
Sets the given function as a hook. The string mask and the number count describe when the hook

* 'c': the hook is called every time Lua calls a function;
* 'r': the hook is called every time Lua returns from a function;
* 'l': the hook is called every time Lua enters a new line of code.
With a count different from zero, the hook is called after every count instructions.
When called without arguments, debug.sethook turns off the hook.
When the hook is called, its first parameter is a string describing the event that has triggered
its call: 'call', 'return' (or 'tail return', when simulating a return from a tail call), 'line',
and 'count'. For line events, the hook also gets the new line number as its second parameter.
Inside a hook, you can call getinfo with level 2 to get more information about the running function
(level 0 is the getinfo function, and level 1 is the hook function), unless the event is 'tail return'.
In this case, Lua is only simulating the return, and a call to getinfo will return invalid data.

next line (see below).
The available formats are
* '*n': reads a number; this is the only format that returns a number instead of a string.
* '*a': reads the whole file, starting at the current position. On end of file, it returns the empty string.
* '*l': reads the next line (skipping the end of line), returning nil on end of file. This is the default format.
* number: reads a string with up to this number of characters, returning nil on end of file. If number is zero, it
reads nothing and returns an empty string, or nil on end of file.

Sets and gets the file position, measured from the beginning of the file, to the position given by offset

* 'end': base is end of file;
In case of success, function seek returns the final file position, measured in bytes from the beginning of the
file. If this function fails, it returns nil, plus a string describing the error.
The default value for whence is 'cur', and for offset is 0. Therefore, the call file:seek() returns the
current file position, without changing it; the call file:seek('set') sets the position to the beginning
of the file (and returns 0); and the call file:seek('end') sets the position to the end of the file, and

* 'line': line buffering; output is buffered until a newline is output or there is any input
from some special files (such as a terminal device).

<Overload retVal="void" descr="
Loads the given module. The function starts by looking into the package.loaded table to
determine whether modname is already loaded. If it is, then require returns the value stored
at package.loaded[modname]. Otherwise, it tries to find a loader for the module.
To find a loader, require is guided by the package.loaders array. By changing this array,
we can change how require looks for a module. The following explanation is based on the
default configuration for package.loaders.
First require queries package.preload[modname]. If it has a value, this value (which should
be a function) is the loader. Otherwise require searches for a Lua loader using the path
stored in package.path. If that also fails, it searches for a C loader using the path stored
in package.cpath. If that also fails, it tries an all-in-one loader (see package.loaders).
Once a loader is found, require calls the loader with a single argument, modname. If the
loader returns any value, require assigns the returned value to package.loaded[modname].
If the loader returns no value and has not assigned any value to package.loaded[modname],
then require assigns true to this entry. In any case, require returns the final value of
package.loaded[modname].
If there is any error loading or running the module, or if it cannot find any loader for
the module, then require signals an error.

string.format('%q', 'a string with ''quotes'' and \n new line')

For instance, if the path is the string

the search for the name foo.a will try to open the files ./foo/a.lua, ./foo/a.lc, and /usr/local/foo/a/init.lua,
