+You can configure the behavior of the script, as well as fine-tune some extensions in order fit your needs, by using environment variables:
 
 | Extension | Environment variable | Description |
 |---|---|---|
-| lzf | IPE_LZF_BETTERCOMPRESSION=1 | By default `install-php-extensions` compiles the `lzf` extension to prefer speed over size; you can use this environment variable to compile it preferring size over speed  |
+| | `IPE_KEEP_SYSPKG_CACHE=1` | By default the script will clear the apt/apk/pear cache in order to save disk space. You can disable it by setting this environment variable |
-| event | IPE_EVENT_NAMESPACE=... | By default the `event` classes are defined in the root namespace. You can use this environment variable to specify a custom namespace |

 ### Adding support to a new PHP extension?

 PHP extensions published on the PECL archive contain a `package.xml` (or `package2.xml`) file describing the supported PHP versions and the options that can be used to compile it.
 When we add support for a new PHP extension, and when a new version of a PHP extension is released, we have to check those constraints.
 
-It's a rather tedious taks, so I developed a project that lets you easily check those constraints: you can find it at https://mlocati.github.io/pecl-info ([here](https://github.com/mlocati/pecl-info) you can find its source code).
