   4 Subject: [PATCH] Makefile: provide an option to not build manpages
   5
   6 The process of generating the vpnc.8 man page consists in running the
   7 vpnc tool itself, and parse its --long-help output. While this is
   8 perfectly fine when building natively, it fails completely when
   9 cross-compiling: the vpnc binary that was built cannot be executed on
  10 the build machine.
  11
  12 In order to support such situations with minimal changes, this patch
  13 adjusts the Makefile to make it understand a MANS variable. By
  14 default, it's defined to "vpnc.8", which means the manpage continues
  15 to be built as usual. However, if it's overriden to be empty, then no
  16 manpage is built.
