what's the rationale for libpcre_8.35 "PROVIDING" pcre?

[Robert P. J. Day]

  i might be overthinking this, but ive noticed a number of "lib*"
recipe files that "PROVIDE" the shorter name. case in point -- in the
current oe-core, the recipe file libpcre_8.35.bb explicitly does this:

PROVIDES += "pcre"

is there a reason for this, other than the obvious allowing to use the
shorter name?

  i did notice that, although the name "libpcre" suggests a shared
library, the recipe file clearly creates a number of packages,
including some that provide command-line utilities:

PACKAGES =+ "libpcrecpp libpcreposix pcregrep pcregrep-doc pcretest pcretest-doc"

  so is there anything to this occasional "lib*" renaming, other than
brevity? thanks.

I suspect the recipe was once called "pcre" but was renamed and the
PROVIDES was for compatibility. There might be something in the history
about that.
