+dnl Find a library (specifically the linkage used in the code fragment),
+dnl searching for it if it is not already in the library path.
+dnl See also CF_ADD_SEARCHPATH.
+dnl
+dnl Parameters (4-on are optional):
+dnl $1 = headers for library entrypoint
+dnl $2 = code fragment for library entrypoint
+dnl $3 = the library name without the "-l" option or ".so" suffix.
+dnl $4 = action to perform if successful (default: update CPPFLAGS, etc)
+dnl $5 = action to perform if not successful
+dnl $6 = module name, if not the same as the library name
+dnl $7 = extra libraries
+dnl
+dnl Sets these variables:
+dnl $cf_cv_find_linkage_$3 - yes/no according to whether linkage is found
+dnl $cf_cv_header_path_$3 - include-directory if needed
+dnl $cf_cv_library_path_$3 - library-directory if needed
