 357 # This makefile has been automatically generated from the OpenSSL distribution.
 358 # This single makefile will build the complete OpenSSL distribution and
 359 # by default leave the 'intertesting' output files in .${o}out and the stuff
 360 # that needs deleting in .${o}tmp.
 361 # The file was generated by running 'make makefile.one', which
 362 # does a 'make files', which writes all the environment variables from all
 363 # the makefiles to the file call MINFO.  This file is used by
 364 # util${o}mk1mf.pl to generate makefile.one.
 365 # The 'makefile per directory' system suites me when developing this
 366 # library and also so I can 'distribute' indervidual library sections.
 367 # The one monster makefile better suits building in non-unix
 368 # environments.
