- * and we want the program to compile on as many systems as possible.
- *
- * If you uncomment this and you figure out how to get it working, please

- * Uncomment the following if you always want to use the -file or
- * -directory options on the command line and never to use a default bubble
- * compiled into the program. This way you would save memory and disk space
- * since if you do use -file or -directory only one bubble will be loaded
- * into memory at any one time (and remember the default bubble is really
- * uncompressed, unlike bubbles in files which can be compressed). This
- * is disabled by default only so people running the program for the first
- * time with no knowldege of the command line options don't get error
- * messages ;)
- *
- * NOTE: You will still need to have a bubbles_default.c file, else the
- * build sequence will fail. Well constructed bubbles_default.c files
- * have #ifdef's which simply exclude everything else in the file at
- * compile time. The bubblestodefault script does this.

- * convenient checking routines which simply aren't called but are left
