If you plan to use the notebook front end as a package editor, be sure
to do the following:
1) When you first load the raw .m file into the notebook, select the
cell bracket that contains the pakcage code and peform the following
front end menu command sequence:
Cell -> Cell Properties -> Initialization Cell
2) Perform the following menu command sequence:
Edit -> Preferences...
3) On the resulting dialog box, set the scope list box to "notebook".
It may read "global", "selection", or "selection's style".
4) In the text field adjacent to the Lookup button, enter
This will expose an option named AutoGeneratedPackage. Set it to
5) Now enter the following text in the Lookup field:
This should expose two adjacent options named:
Set both of these options to have the False value.
6) Close the dialog box.
7) Save the notebook with the same base name as you want the package to
be (e.g. MyPackage.m -> MyPackage.nb).
Now whenever you save the notebook, the changes you made to any
initialization cells are also exported out to a companion package with
the same base name. Doing a File -> Save As Special -> Package Format
saves out initialization cell contents and other cell contents
