" . " is short-hand for "source", which you can think of as an "include"
statement. ;-)

>From the bash man page:

         .  filename [arguments]
        source filename [arguments]
               Read  and  execute  commands from filename in the current shell
               environment and return the exit status of the last command exe-
               cuted  from  filename.   If  filename does not contain a slash,
               file names in PATH are used to find  the  directory  containing
               filename.   The  file  searched  for  in  PATH need not be exe-
               cutable.  When bash is not in posix mode, the current directory
               is  searched  if  no  file is found in PATH.  If the sourcepath
               option to the shopt builtin command is turned off, the PATH  is
               not  searched.   If any arguments are supplied, they become the
               positional parameters when filename is executed.  Otherwise the
               positional  parameters are unchanged.  The return status is the
               status of the last command exited within the script  (0  if  no
               commands  are  executed), and false if filename is not found or
               cannot be read.
