- *
- *  The -S option prevents an interactive shell being started
- *  after all arguments have been processed.
- *
- *  Previous versions accepted a -s option to cause a shell
- *  to be started; this option is still accepted but ignored
- *  since a command shell is now started by default.
- *
- *  Access Security can be enabled with the -a option giving
- *  the name of the configuration file; if any macros were
- *  set with -m before the -a option was given, they will be
- *  used as access security substitution macros.
- *
- *  Any number of -m and -d arguments can be interspersed;
- *  the macros are applied to the following .db files.  Each
- *  later -m option causes earlier macros to be discarded.
- *
- *  The -x option loads the softIocExit.db with the macro
- *  IOC set to the string provided.  This database contains
- *  a subroutine record named $(IOC):exit which has its field
- *  SNAM set to "exit".  When this record is processed, the
- *  subroutine that runs will call epicsExit() with the value
- *  of the field A determining whether the exit status is
- *  EXIT_SUCCESS if (A == 0.0) or EXIT_FAILURE (A != 0.0).
- *
- *  A st.cmd file is optional.  If any databases were loaded
- *  the st.cmd file will be run *after* iocInit.  To perform
- *  iocsh commands before iocInit, all database loading must
- *  be performed by the script itself, or by the user from
- *  the interactive IOC shell.
