			"usefull for the last pair, as they are worked from left to right.<p>".
			"First example: <b>1${ASep}private${PSep}public</b><br>".
			"This will translate a '1' in the CVS field to 'privat' and everything else to 'public'.<p>".
			"Patterns as well as the replacement can be regular expressions (the replacement is done via ereg_replace). ".
			"If, after all replacements, the value starts with an '@' the whole value is eval()'ed, so you ".
			"may use all php, phpgw plus your own functions. This is quiet powerfull, but <u>circumvents all ACL</u>.<p>".
			"Example using regular expressions and '@'-eval(): <br><b>$mktime_lotus</b><br>".
			"It will read a date of the form '2001-05-20 08:00:00.00000000000000000' (and many more, see the regular expr.). ".

			"In addintion to the fields assign by the pattern of the reg.exp. you can use all other CSV-fields, with the ".
			"syntax <b>${CPre}CVS-FIELDNAME$CPos</b>. Here is an example: <br>".
			"<b>.+$ASep${CPre}Company$CPos: ${CPre}NFamily$CPos, ${CPre}NGiven$CPos$PSep${CPre}NFamily$CPos, ${CPre}NGiven$CPos</b><br>".
			"It is used on the CVS-field 'Company' and constructs a something like <i>Company: FamilyName, GivenName</i> or ".

			"You can use the 'No CVS #'-fields to assign cvs-values to more than on field, the following example uses the ".

			"<b>@substr(${CPre}Note$CPos,0,60).' ...'</b><p>".
