When you click the bibtex button, bibtex will run. Its standard output will appear in the window where you started abala. Log files, aux files, etc. will be written in working directory. For example, abala paper common would produce latex, dvips, lpr, etc. When you click the xdvi button, xdvi will run.
Some people prefer xdvi to ghostscript, to avoid the dvips step.
When you click the lpq button, the lpq command will display the default printer's queue, in the window where you started abala. When you click the lpr button, the postscript file will be sent to the default printer. When you click the exit button, yume will exit and the menu will disapear. Although abala stands for A Basic Latex menu, a pre-existing webpage about the name abala fails to mention this simple fact. Please report any bugs or suggestions for improvements via the yume improvement system.
