.SH DESCRIPTION
.IX Header "DESCRIPTION"
Debian::Control::Stanza::CommaSeparated abstracts handling of comma-separated
list of values, often found in \fIdebian/control\fR file fields like \fIUploaders\fR.
Note that the various dependency fields in \fIdebian/control\fR also use
comma-separated values, but the Debian::Dependencies class is more suitable
for these as it is for example also capable of finding overlapping dependency
declarations.
.SH CONSTRUCTOR
.IX Header "CONSTRUCTOR"
.IP "new (initial values)" 4
.IX Item "new (initial values)"
The initial values list is parsed and may contain strings that are in fact
comma-separated lists. These are split appropriately using Text::ParseWords'
\&\fIquotewords\fR routine.
.SH METHODS
.IX Header "METHODS"
.IP as_string 4
.IX Item "as_string"
Returns text representation of the list. A simple join of the elements by \f(CW\*(C`, \*(C'\fR.
.Sp
The same function is used for overloading the stringification operation.
.ie n .IP "add \fR\fI@items\fR\fI\fR" 4
.el .IP "add \fR\f(CI@items\fR\fI\fR" 4
.IX Item "add @items"
Adds the given items to the list. Items that are already present are not added,
keeping the list unique.
.IP sort 4
.IX Item "sort"
A handy method for sorting the list.
