=head1 RUNNING THE TOOL FROM THE COMMAND LINE
-=head2 CREATING A NEW TALK
-
-Tech Talk PSE talks are just directories containing C<*.html> and
-C<*.sh> (shell script) files:
-
- 0010-introduction.html
- 0500-demonstration.sh
- 9900-conclusion.html
-
-The filenames that Tech Talk PSE considers to be slides have to match
-the regular expression:
-
- ^(\d+)(?:-.*)\.(html|sh)$
-
-(any other file or subdirectory is ignored). Shell scripts I<must>
-be executable.
-
-You can create a new talk just by creating an empty directory and
-adding files as above, but you can also create a useful skeleton talk
-like this:
-
- mkdir talk
- cd talk
- techtalk-pse --new
-
-The C<--new> flag will refuse to overwrite any existing files, so you
-should run it in an empty directory.
-
-=head2 DISPLAYING AN EXISTING TALK
-
-To display or run a talk, change into the directory containing all
-those files and run the C<techtalk-pse> command:
+A Tech Talk PSE talk is not a single file, but a directory full of
+files. (If you want to start a new talk, see the L</TUTORIAL> section
+below). To display or run the talk, change into the directory
+containing all those files and run the C<techtalk-pse> command:
cd /path/to/talk/; techtalk-pse
