 7+# colorize
 8+
 9+With this plugin you can syntax-highlight file contents of over 300 supported languages and other text formats.
10+
11+To use it, add colorize to the plugins array of your zshrc file:
12+```
13+plugins=(... colorize)
14+```
15+
16+## Usage
17+
18+* `ccat <file> [files]`: colorize the contents of the file (or files, if more than one are provided). If no arguments are passed it will colorize the standard input or stdin.
