There are a lot of libraries out there and, invariably, they do a lot of things that you don't need or in a manner that you don't like. Thus, they feel bloated. One example would be Prototype. Recently, I discovered it has a Template class. At first, I thought it was a template engine similar to Smarty for PHP, but it turned out I was wrong. It's just a method of returning formatted strings wrapped in a fancy class. If you're familiar with C, C++, Objective C, Perl, Python, PHP, bash, awk, etc. you're probably aware of the printf function, used to output formatted strings.

"\t" (ASCII 9 (0x09)), a tab.
"\n" (ASCII 10 (0x0A)), a new line (line feed).
"\r" (ASCII 13 (0x0D)), a carriage return.
"\0" (ASCII 0 (0x00)), the NUL-byte.
"\x0B" (ASCII 11 (0x0B)), a vertical tab.
