 * @return string the requested path or the converted path
 | 
						|
 *
 | 
						|
 * Notes about the current behaviour model:
 | 
						|
 * 1. Windows back-slashes are converted to slashes in the result.
 | 
						|
 * 2. A semi-absolute web-path is detected by its leading slash. On Linux systems, absolute system paths start with
 | 
						|
 * a slash too, so an additional check about presence of leading system server base is implemented. For example, the function is
 | 
						|
 * able to distinguish type difference between /var/www/chamilo/courses/ (SYS) and /chamilo/courses/ (REL).
 | 
						|
 * 3. The function api_get_path() returns only these three types of paths, which in some sense are absolute. The function has
 | 
						|
 * no a mechanism for processing relative web/system paths, such as: lesson01.html, ./lesson01.html, ../css/my_styles.css.
 | 
						|
 * It has not been identified as needed yet.
 | 
						|
 * 4. Also, resolving the meta-symbols "." and ".." within paths has not been implemented, it is to be identified as needed.
 | 
						|
 *
 | 
						|
 * Vchamilo changes : allow using an alternate configuration
 | 
						|
 * to get vchamilo  instance paths

/**
 | 
						|
 * Parse info file format. (e.g: file.info).
 | 
						|
 *
 | 
						|
 * Files should use an ini-like format to specify values.
 | 
						|
 * White-space generally doesn't matter, except inside values.
 | 
						|
 * e.g.
 | 
						|
 *
 | 
						|
 * @verbatim
 | 
						|
 *   key = value
 | 
						|
 *   key = "value"
 | 
						|
 *   key = 'value'
 | 
						|
 *   key = "multi-line
 | 
						|
 *
 | 
						|
 *   value"
 | 
						|
 *   key = 'multi-line
 | 
						|
 *
 | 
						|
 *   value'
 | 
						|
 *   key
 | 
						|
 *   =
 | 
						|
 *   'value'
 | 
						|
 * @endverbatim
 | 
						|
 *
 | 
						|
 * Arrays are created using a GET-like syntax:
 | 
						|
 *
 | 
						|
 * @verbatim
 | 
						|
 *   key[] = "numeric array"
 | 
						|
 *   key[index] = "associative array"
 | 
						|
 *   key[index][] = "nested numeric array"
 | 
						|
 *   key[index][index] = "nested associative array"
 | 
						|
 * @endverbatim
 | 
						|
 *
 | 
						|
 * PHP constants are substituted in, but only when used as the entire value:
 | 
						|
 *
 | 
						|
 * Comments should start with a semi-colon at the beginning of a line.
 | 
						|
 *
 | 
						|
 * This function is NOT for placing arbitrary module-specific settings. Use
 | 
						|
 * variable_get() and variable_set() for that.
 | 
						|
 *
 | 
						|
 * Information stored in the module.info file:
 | 
						|
 * - name: The real name of the module for display purposes.
 | 
						|
 * - description: A brief description of the module.
 | 
						|
 * - dependencies: An array of shortnames of other modules this module depends on.
 | 
						|
 * - package: The name of the package of modules this module belongs to.
 | 
						|
 *
 | 
						|
 * Example of .info file:
 | 
						|
 * <code>
 | 
						|
 * @verbatim
 | 
						|
 *   name = Forum
 | 
						|
 *   description = Enables threaded discussions about general topics.
 | 
						|
 *   dependencies[] = taxonomy
 | 
						|
 *   dependencies[] = comment
 | 
						|
 *   package = Core - optional
 | 
						|
 *   version = VERSION
 |

 * @endverbatim
