   3 # Replace #! interpreters in scripts by what we actually have.
   4 #
   5 # Standard templates for bash, perl, python,... are included out of
   6 # the box, others can easily be added per port.
   7 #
   8 # Feature:      shebangfix
   9 # Usage:        USES=shebangfix
  10 #
  11 # To specify that ${WRKSRC}/path1/file and all .pl files in ${WRKSRC}/path2
  12 # should be processed:
  13 #
  14 #   SHEBANG_FILES=      path1/file path2/*.pl
  15 #
  16 # To define custom shebangs to replace, use the following (note that
  17 # shebangs with spaces should be quoted):
  18 #
  19 #   perl_OLD_CMD=       /usr/bin/perl5.005 "/usr/bin/setenv perl5.005"
  20 #
  21 # To define a new shebang scheme add the following to the port Makefile:
  22 #
  23 #   SHEBANG_LANG=       lua
  24 #   lua_OLD_CMD=        /usr/bin/lua
  25 #   lua_CMD=    ${LOCALBASE}/bin/lua
  26 #
  27 # To override a definition, for example replacing /usr/bin/perl by
  28 # /usr/bin/env perl, add the following:
  29 #
  30 #   perl_CMD=   ${SETENV} perl
