is it "PROVIDES =" or "PROVIDES +=" for setting an alternate name?

["Robert P. J. Day" <rpjday@crashcourse.ca>]

  i notice that the OE-core codebase likes to mix these two forms of
using PROVIDES. for instance, for a number of libraries to provide
their basename, i see stuff like:

recipes-graphics/xorg-lib/libxmu_1.1.2.bb:PROVIDES = "xmu"
recipes-graphics/xorg-lib/libice_1.0.8.bb:PROVIDES = "ice"
recipes-graphics/xorg-lib/libxdamage_1.1.4.bb:PROVIDES = "xdamage"
recipes-graphics/xorg-lib/libxfont_1.4.7.bb:PROVIDES = "xfont"
recipes-graphics/xorg-lib/libxdmcp_1.1.1.bb:PROVIDES = "xdmcp"

  on the other hand, there is the occasional example of the same thing
that uses "PROVIDES +=" instead:

recipes-support/libpcre/libpcre_8.35.bb:PROVIDES += "pcre"

is there a deliberate distinction made in the recipes between these
two forms?
