<UL>
<LI>DfmToLfm now supports converting a Lazarus form file too, as a way
to create more than one version of the same form, for example to conditionally
include a different version based on widgetset target. For example, you could
do this in a form's unit:
<PRE>
{$IFNDEF LCLCarbon}
{$R *.lfm} //include generic form with Windows and Linux
{$ELSE}
{$R *.mac.lfm} //include prettied form with Mac (-m -s switches)
{$ENDIF}

(*
Note: This converter can also convert a Lazarus form file to
another Lazarus form file (.lfm -->.lfm). This can be useful
if you need to conditionally include a different form depending
on widgetset target. Example:
{$IFNDEF LCLCarbon}
{$R *.lfm} //include generic form with Windows and Linux
{$ELSE}
{$R *.mac.lfm} //include prettied form with Mac (-m -s switches)
{$ENDIF}
In this case, you would make changes in Lazarus only to the
generic form file, then convert it to use with Mac:
dfmtolfm myform.lfm myform.mac.lfm -m -s
