Adds some field name/version pairs. Even if there are |
150 |
one or more C<product>s whose name is same as C<$name> |
151 |
(case sensible), given name/body pairs are ADDed. Use C<replace> |
152 |
to remove C<old> one. |
153 |
|
154 |
Instead of C<$version>, you can pass array reference. |
155 |
[0] is used for C<version>, the others are saved as elements |
156 |
of C<comment>. |
157 |

C<-prepend> options is available. C<1> is default. |
