如何使用groff在unix手册页中添加空行？

Question

我尝试了以下操作但它不起作用：

.SH ADD A NEW TEST
Everytime you invoke a command within the shell,
this is what actually happens: the shell search for a folder
named as your command inside the directory
.B path/to/framework/Tests
or any subfolder,
if it finds such a folder, it will search for a file called
main.pl and will launch it.
.br
.br
Adding a new test is easy as create a new folder, put a main.pl
file inside it and invoke the folder name. Of course, for a better
integration with the whole system you should follow
some guide lines. Invoke the command
.B skeleton
to find out where the skeleton file is installed in your
system. Have a look to that file. It's well commented and
cover all possibile case and scenarios. Use it as a model to write
your own test.

第二个.br被忽略了。

当段落开始时，我可以使用.PP来完成它。
