#  The default target is 'drivers', which will build all the vbeaf.drv       #
#  files. Run 'make cardname/vbeaf.drv' to compile a specific driver.        #
#                                                                            #
#  To build the install program for a binary distribution, run 'make all'.   #
#  This requires the Allegro utilties dat.exe and exedat.exe (from the       #
#  allegro/tools/ directory) to be located somewhere on your path.           #
#                                                                            #
#  To reconvert the documentation from the ._tx source, run "make docs".     #
#  This needs the Allegro makedoc utility (allegro/obj/djgpp/makedoc.exe)    #
#  to be located somewhere on your path.                                     #
#                                                                            #
#  The 'clean' target requires the rm utility from GNU fileutils.            #
#                                                                            #
