+ * execunix.c - execute a shell script on UNIX
+ *
+ * If $(JAMSHELL) is defined, uses that to formulate execvp().
+ * The default is:
+ *
+ *  /bin/sh -c %
+ *
+ * Each word must be an individual element in a jam variable value.
+ *
+ * In $(JAMSHELL), % expands to the command string and ! expands to
+ * the slot number (starting at 1) for multiprocess (-j) invocations.
+ * If $(JAMSHELL) doesn't include a %, it is tacked on as the last
+ * argument.
+ *
+ * Don't just set JAMSHELL to /bin/sh - it won't work!
+ *
+ * External routines:
+ *  exec_cmd()  - launch an async command execution.
+ *  exec_wait() - wait and drive at most one execution completion.
+ *
+ * Internal routines:
+ *  onintr() - bump intr to note command interruption.
+ *
+ * 04/08/94 (seiwald) - Coherent/386 support added.
+ * 05/04/94 (seiwald) - async multiprocess interface
+ * 01/22/95 (seiwald) - $(JAMSHELL) support
