        ''' 
DESCRIPTION

    "set_bond" changes per-bond settings for all bonds which exist
    between two selections of atoms.

USAGE

    set_bond name, value, selection1 [, selection2 ]

ARGUMENTS

    name = string: name of the setting

    value = string: new value to use

    selection1 = string: first set of atoms

    selection2 = string: seconds set of atoms {default: (selection1)}

EXAMPLE

    set_bond stick_transparency, 0.7, */n+c+ca+o


NOTES

    The following per-bond settings are currently implemented.  Others
    may seem to be recognized but will currently have no effect when
    set at the per-bond level.
    
    * valence
    * line_width
    * line_color
    * stick_radius

    Note that if you attempt to use the "set" command with a per-bond
    setting over a selection of atoms, the setting change will appear
    to take, but no change will be observed.

        '''
DESCRIPTION

    "set" changes global, object, object-state, or per-atom settings.

USAGE

    set name [,value [,selection [,state ]]]

ARGUMENTS

    name = string: setting name

    value = string: a setting value {default: 1}

    selection = string: name-pattern or selection-expression
    {default:'' (global)}

    state = a state number {default: 0 (per-object setting)}

EXAMPLES

    set orthoscopic

    set line_width, 3

    set surface_color, white, 1hpv
    
    set sphere_scale, 0.5, elem C

NOTES

    The default behavior (with a blank selection) is global.  If the
    selection is "all", then the setting entry in each individual
    object will be changed.  Likewise, for a given object, if state is
    zero, then the object setting will be modified.  Otherwise, the
    setting for the indicated state within the object will be
    modified.

    If a selection is provided as opposed to an object name, then the
    atomic setting entries are modified.

    The following per-atom settings are currently implemented.  Others
    may seem to be recognized but will have no effect when set on a
    per-atom basis.
    
    * sphere_color
    * surface_color
    * mesh_color
    * label_color
    * dot_color
    * cartoon_color
    * ribbon_color
    * transparency (for surfaces)
    * sphere_transparency
    
    Note that if you attempt to use the "set" command with a per-bond
    setting over a selection of atoms, the setting change will appear
    to take, but no change will be observed.  Please use the
    "set_bond" command for per-bond settings.

        '''
DESCRIPTION

    "unset" clears a setting and restores its default value.

    WARNING: The behavior for global settings changed in PyMOL 2.5.
    Previously, "unset settingname" would set the global value of
    "settingname" to zero/off instead of the default value.
    To set a setting to zero, do "set settingname, 0".

USAGE

    unset name [,selection [,state ]]

EXAMPLE

    unset orthoscopic

    unset surface_color, 1hpv

    unset sphere_scale, elem C
    
NOTES

    If selection is not provided, unset changes the named global
    setting to its default value.

    If a selection is provided, then "unset" undefines per-object,
    per-state, or per-atom settings.
