+/*
+ * Program to generate the so-thresh testcase,
+ * including associated linked-against shared libraries.
+ * Build as:
+ *
+ * cc -g -o gen-so-thresh gen-so-thresh.c
+ *
+ * Invoke as:
+ *
+ * gen-so-thresh
+ *
+ * It will put all the code in the current directory (".").
+ *
+ * A makefile can also be generated if the -makemake option is used.
+ * To use the makefile:
+ *
+ * make -f so-thresh.mk all
+ *
+ * The name of the application is
+ *
+ * so-thresh
+ *
+ * (Revised from a program by John Bishop. --rehrauer)
