improvements to handling of $oldroot

Try to determine $oldroot automatically, by looking for a folder called
.Mail or Mail in your homedir. Failing that, the root can be specified
with a command-line option.

166
167 Options:
168   -debug   | -d        debug mode
169   -help    | -h        brief help message
170   -man     | -m        full documentation

172
173=head1 OPTIONS
174
175=over 4
176
177=item B<-debug>
178
179Enter debug mode. This will print what would be done. No commands are executed,
180so this is safe to use when testing.
181
182=item B<-help>
183
184Print a brief help message and exits.
185
186=item B<-man>
187
188Prints the manual page and exits.
189
190=item B<-oldroot>
191
192Specify where your B<KMail> mailboxes are to be found. By default assumes a
193folder called F<.Mail> or F<Mail> in your homedir, preferring F<.Mail> if it
194exists.
195
196=back
197
198=head1 DESCRIPTION
199
200B<md2mb.pl> will import a B<kmail> maildir environment, and transform it into a
201B<thunderbird> one. It relies on either B<formail> or B<procmail> being
202available in your search path, and will preferentially use B<formail>.
203
204By default, B<md2mb.pl> assumes that your B<kmail> mailboxes are stored in a
205folder called F<.Mail> or F<Mail> in your homedir. If this assumption is
206incorrect, you need to specify the correct folder with B<-oldroot>.
