+/**
+ * SquirrelMail html translation table documentation
+ *
+ * SquirrelMail provides own implementation of htmlentities() and
+ * get_html_translation_table() functions. Functions are called
+ * sq_get_html_translation_table() and sq_htmlentities(). They are 
+ * included in functions/strings.php
+ *
+ * sq_htmlentities uses same syntax as functions available in php 4.1.0
+ * sq_get_html_translation_table adds third option that sets charset.
+ *
+ * string sq_htmlentities ( string string [, int quote_style [, string charset]])
+ * array sq_get_html_translation_table ( int table [, int quote_style [, string charset]])
+ *
+ * If sq_get_html_translation_table function is called with HTML_SPECIALCHARS option,
+ * it returns us-ascii translation table. If it is called with HTML_ENTITIES option,
+ * it returns translation table defined by charset. Function defaults to us-ascii charset
+ * and not to iso-8859-1.
+ *
+ * Why own functions are used instead of htmlspecialchars() and 
+ * htmlentities() provided by php.
+ *
+ * a) removes dependency on options available only in php v.4.1+
+ * b) default behavior of htmlentities() is disastrous in non iso-8859-1 environment.
+ * c) provides better control of transformations.
+ *
