+** File: anonfm.c
+** Description: Test anonymous file map 
+**
+** Synopsis: anonfm [options] [dirName]
+**
+** Options:
+** -d   enable debug mode
+** -h   display a help message
+** -s <n>  size of the anonymous memory map, in KBytes. default: 100KBytes.
+** -C 1 Operate this process as ClientOne() 
+** -C 2 Operate this process as ClientTwo()
+**
+** anonfn.c contains two tests, corresponding to the two protocols for
+** passing an anonymous file map to a child process.
+**
+** ServerOne()/ClientOne() tests the passing of "raw" file map; it uses
+** PR_CreateProcess() [for portability of the test case] to create the
+** child process, but does not use the PRProcessAttr structure for
+** passing the file map data.
+**
+** ServerTwo()/ClientTwo() tests the passing of the file map using the
+** PRProcessAttr structure.
