- FIXME: Go into more depth about the -p0 option...
+ The <parameter>-p0</parameter> option to <command>patch</command>
+ tells it to keep the full file name from the patch file. For example,
+ if the file name in the patch file was
+ <filename>wine/programs/clock/main.c</filename>.
+ Setting the <parameter>-p0</parameter> option would apply the patch
+ to the file of the same name i.e.
+ <filename>wine/programs/clock/main.c </filename>.
+ Setting the <parameter>-p1</parameter> option would strip off the
+ first part of the file name and apply
+ the patch instead to <filename>programs/clock/main.c </filename>.
+ The <parameter>-p1</parameter> option would be useful if you named
+ your top level wine directory differently to the person who sent you
+ the patch. For the <parameter>-p1</parameter> option
+ <command>patch</command> should be run from the top level wine directory.
