I am using the
resume document class to write my resume.
Since I want to make my resume fit in one page, I would like to decrease the spacing at the top of the document but keep the bottom, right and left margin spacings to the default value.
Googling around, I found that the following lines added at the top of the document
should do the trick. However, I want to change only the top margin values and keep the bottom, left and right margins the same. How do I specify the default values to the marginsize command for the < bottom >, < left > and < right > fields? A simple example will be very helpful.
