.SH OPTIONS
.TP
.B -l BASE-NAME, --list=BASE-NAME
List operations below BASE-NAME. This prints a one-line summary of every
operation in vips below the class BASE-NAME, where BASE-NAME may be a full
vips class name, or a nickname.
If BASE-NAME is not supplied, this will list all classes below VipsOperation.
.TP
.B -p PLUGIN, --plugin=PLUGIN
Load PLUGIN. Note that plugins in $VIPSHOME/lib are loaded automatically.

.SH COMMANDS
.TP
.B list PACKAGE
List operations defined in PACKAGE. PACKAGE can also be "classes", "packages"
or "all".
.TP
.B cpph PACKAGE
Print C++ header for PACKAGE. PACKAGE can also be a function name, or "all".
.TP
.B cppc PACKAGE
Print C++ binding for PACKAGE. PACKAGE can also be a function name, or "all".
.TP
.B operation-name operation-arguments
Execute a named operation, for example im_invert, or add. Names prefixed with
"im_" are called via the vips7 interface, names without the prefix use the new
vips8 interface.
Execute a named operation, for example add.
