// Turns "apt-get install" lines into clickable apturl links for
// installing Ubuntu and Debian GNU/Linux packages This extension is
// intended to ease the life of Ubuntu/Debian users who browse the
// Internet searching for software, tutorials, etc.
//
// Apt: urls are a way to install packages by using a protocol handler to
// read the list of packages to install.
//
// This extension will turn lines of text describing commands for
// installation into clickable links that allow you to install the
// packages with just 2 clicks.
//
// More info about AptUrl can be found here:
// https://help.ubuntu.com/community/AptURL

(function() {
/* == findAndReplace ==
* No library or framework is required to use this function, it's entirely stand-alone. The function requires
* two parameters, the third one is optional:
*
* * searchText - This can either be a string or a regular expression. Either way, it will eventually become a
* RegExp object. So, if you wanted to search for the word "and" then that alone would not be appropriate - all
* words that contain "and" would be matched so you need to use either the string, \\band\\b or the regular
* expression, /\band\b/g to test for word boundaries. (remember the global flag)
*
* * replacement - This parameter will be directly passed to the String.replace function, so you can either have
* a string replacement (using $1, $2, $3 etc. for backreferences) or a function.
*
* * searchNode - This parameter is mainly for internal usage but you can, if you so desire, specify the node
* under which the search will take place. By default it's set to document.body.
