### This is a replacement for configure when installing
### CCP4 binaries.
### When updating this script for new releases check for
### new configure features which might need to be here
### too.

###
###   CCP4 licensing and conditions.
###
### A complete new section for licensing
### Removing or attempting to bypass this section in the BINARY.setup script 
### is deemed as agreeing to the conditions outlined in $CCP4/license.txt

agreed=no
ans=n
user=`whoami`

### has someone else we (know about) agreed to the ccp4 conditions before?
### and if so make sure the the home dir has agreement file
if test -f .agree2ccp4; then
   eval touch ${HOME}/.agree2ccp4;
   if test -w .agree2ccp4; then 
      echo $user `date` >> .agree2ccp4;   
   fi
   if test -w ${HOME}/.agree2ccp4; then
      date >> ${HOME}/.agree2ccp4;
   fi
   agreed=yes
fi

### has the user agreed to the ccp4 condition's before?
if test $agreed = "no"; then
   if test -f ${HOME}/.agree2ccp4; then
      eval touch .agree2ccp4
      if test -w ${HOME}/.agree2ccp4; then

      agreed=yes

### so if this site, as far as we know has never agreed to ccp4 
### conditions then they must!
