The LaTeX class drexel-thesis is distributed in the docstrip file
drexel-thesis.dtx with the install file drexel-thesis.ins.
For more information on the docstrip format, look here and here.
To generate the class file drexel-thesis.cls, the template files,
the PDF documentation, and a bunch of intermediate files, run:
$ make
in this directory. You'll need to install drexel-thesis.cls
somewhere in your texmf tree (or just dump it into the top level
of your thesis directory). Running:
$ make temp-clean
will get rid of the intermediate files.
We also package the LyX template drexel-thesis.layout to assist
those using the drexel-thesis template with LyX.
For more elaborate examples, see the samples in the DissertationDocs repository.
Happy TeXing!
