+@subsection qsrv_aslib Access Security
+
+QSRV will enforce an optional access control policy file (.acf) loaded by the usual means (cf. asSetFilename() ).
+This policy is applied to both Single and Group PVs.  With Group PVs, restrictions are not defined for the group,
+but rather for the individual member records.  The same policy will be applied regardess of how a record
+is accessed (individually, or through a group).
+
+Policy application differs from CA (RSRV) in several ways:
+
+* Client hostname is always the numeric IP address.  HAG() entries must either contained numeric IP addresses,
+or that asCheckClientIP=1 flag must be set to translate hostnames into IPs on ACF file load (effects CA server as well).
+This prevents clients from trivially forging "hostname".
+* In additional to client usernames.  UAG definitions may contained items beginning with "role/" which are matched
+against the list of groups of which the client username is a member.  Username to group lookup is done internally
+to QSRV, and depends on IOC host authentication configuration.  Note that this is still based on the client provided
+username string.
+
+@code
+UAG(special) {
+  someone, "role/op"
+}
+@endcode
+
+The "special" UAG will match CA or PVA clients with the username "someone".
+It will also match a PVA client if the client provided username is a member
+of the "op" group (supported on POSIX targets and Windows).

- *	[-m macro=value,macro2=value2] [-d file.db]
- *	[-x prefix] [st.cmd]

- *  If used the -D option must come first, and specify the

- *
- *  Usage information will be printed if -h is given, then
- *  the program will exit normally.
- *
- *  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.
