.SH DESCRIPTION
.PP
Discovers and connects to InfiniBand SCSI RDMA Protocol (SRP) targets in an IB fabric.
-Each srp_daemon instance operates on one local port. Upon boot it performs a full rescan of the fabric then waits for an srp_daemon event. An srp_daemon event can be a join of a new machine to the fabric, a change in the capabilities of a machine, an SA change, or an expiration of a predefined timeout.
+Each srp_daemon instance operates on one local port. Upon boot it performs a
+full rescan of the fabric and then waits for an srp_daemon event. An
+srp_daemon event can be a join of a new machine to the fabric, a change in the
+capabilities of a machine, an SA change, or an expiration of a predefined
+timeout.
-When a new machine joins the fabric, srp_daemon checks if it is a target. When there is a change of capabilities, srp_daemon checks if the machine has turned into a target. When there is an SA change or a timeout expiration, srp_daemon performs a full rescan of the fabric.
+When a new machine joins the fabric, srp_daemon checks if it is an SRP
+target. When there is a change of capabilities, srp_daemon checks if the
+machine has turned into an SRP target. When there is an SA change or a timeout
+expiration, srp_daemon performs a full rescan of the fabric.
-For each target srp_daemon finds, it checks if it should connect to this target according to its rules (default rules file is @CMAKE_INSTALL_FULL_SYSCONFDIR@/srp_daemon.conf) and if it is already connected to the local port. If it should connect to this target and if it is not connected yet, srp_daemon can either print the target details or connect to it.

From https://liw.fi/manpages/, about the SYNOPSIS section: Font usage is important here, and carries information. All the parts that are in bold are things that the user is expected to write verbatim. Italic indicates values the user is expected to fill in. Normal font is used for syntax meta-characters: for the brackets that indicate optionality, and the ellipsis that indicates repetition. Additionally, change the identifiers that refer to arguments to lower case.
