 back to this one, the quoting "fix" for quoting +proj4 terms in 6.5svn
 doesn't work,
 e.g. in m.proj.

 in /bin/sh:
 {{{
  mkdir "/tmp/nad test"
  cp "$GISBASE"/etc/nad/nzgd2kgrid0005.gsb "/tmp/nad test/"

  IN_PROJ="'+proj=nzmg' '+lat_0=-41' '+lon_0=173' '+x_0=2510000'
 '+y_0=6023150' '+no_defs' '+a=6378388' '+rf=297' '+nadgrids=/tmp/nad
 test/etc/nad/nzgd2kgrid0005.gsb' '+to_meter=1'"

  OUT_PROJ="+proj=longlat +datum=WGS84"
 }}}

 feed a point to cs2cs:
 {{{
  echo "2006797  5490896" | cs2cs -w5 $IN_PROJ  +to $OUT_PROJ
 Using from definition:
 Rel. 4.6.0, 21 Dec 2007
 <cs2cs>:
 projection initialization failure
 cause: no arguments in initialization list
 program abnormally terminated
 }}}

 same thing, but expanded:
 {{{
  echo "2006797  5490896" | cs2cs -w5 '+proj=nzmg' '+lat_0=-41'
 '+lon_0=173' \
    '+x_0=2510000' '+y_0=6023150' '+no_defs' '+a=6378388' '+rf=297' \
    '+nadgrids=/tmp/nad test/nzgd2kgrid0005.gsb' '+to_meter=1' \
    +to +proj=longlat +datum=WGS84
 166d32'36.78939"E       45d36'42.47115"S 0.000


 I've tried a number of permutations of eval, `echo $IN_PROJ`, and
 different flavours of quoting styles, but I just can't seem to get the
 literal expansion to work.


 any ideas?

 thanks,
 Hamish
