+ * Here is a procedure that reads the .pk file into 'pkbuffer'. Other than
+ * insuring that the initial two bytes are 247 and 89 (the pk_pre command,
+ * followed by the current .pk format identifier), it does no format checks.
+ * If the corresponding .pk file doesn't fit into pkbuffer, 'dvi2pcl' will be
+ * aborted. In this case MAXPKSIZE has to be increased by an appropriate
+ * amount and 'dvi2pcl' has to be recompiled. At this state the choosen value
+ * of MAXPKSIZE will serve all existing .pk files but for future .pk font
+ * files this might happen.
