		"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 '@' AND you have admin rights the whole value is eval()'ed, so you ".
		"may use php, eGroupWare or 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.). ".

		"${VPre} insted of a backslash (I couldn't get backslash through all the involved templates and forms.) ".
		"plus the field-number of the pattern.<p>".
		"In addintion to the fields assign by the pattern of the reg.exp. you can use all other CSV-fields, with the ".
		"syntax <b>${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 ".
		"cvs-field 'Note' (which gots already assingned to the description) and construct a short subject: ".
		"<b>@substr(${CPre}Note$CPos,0,60).' ...'</b><p>".
