 The preprocessor has access to the following variables :

 * ````output```` : the current preprocessor output string.
-* ````import(module[, [args, autoRequire]])```` : a function which import a module. This is equivalent to use _require(module)_ in the Candran code, except the module will be embedded in the current file. _args_ is an optional preprocessor arguments table for the imported module (current preprocessor arguments will be inherited). _autoRequire_ (boolean, default true) indicate if the module should be automaticaly loaded in a local variable or not. If true, the local variable will have the name of the module.
+* ````import(module[, [options])```` : a function which import a module. This should be equivalent to using _require(module)_ in the Candran code, except the module will be embedded in the current file. _options_ is an optional preprocessor arguments table for the imported module (current preprocessor arguments will be inherited). Options specific to this function: ```loadLocal``` (default ```true```): ```true``` to automatically load the module into a local variable (i.e. ```local thing = require("module.thing")```); ```loadPackage``` (default ```true```): ```true``` to automatically load the module into the loaded packages table (so it will be available for following ```require("module")``` calls).
 * ````include(filename)```` : a function which copy the contents of the file _filename_ to the output.
 * ````write(...)```` : write to the preprocessor output. For example, ````#print("hello()")```` will output ````hello()```` in the final file.
 * ```placeholder(name)``` : if the variable _name_ is defined in the preprocessor environement, its content will be inserted here.

 ### Compiling the library
 The Candran library itself is written is Candran, so you have to compile it with an already compiled Candran library.
