This package provides an essential feature to LaTeX that has been missing for too long. It adds a coffee stain to your documents. A lot of time can be saved by printing stains directly on the page rather than adding it manually. You can choose from four different stain types.

This example shows how to generate multiple bibliography sections with the bibtopic package. Each bibliography section can have its own .bib file. This can be very useful in books or theses, if you'd like one references section per chapter, and also in grant and research proposals. See the package documentation for more information.

PSTricks provides a number of built in functions to enable the quick creation of figures, graphs and diagrams in LaTeX. Here we see how to use the built in command for drawing a circle.

Following on from example 4 which showed how to plot the graph of a function in LaTeX using pstricks, here we extend the example to show how trig functions such as cos, sin and tan can be plotted.
