rem US Patent 6720962
rem This script extracts the current Shave version string from the
rem shaveVersion.mel script file and place it into the 'shaveVersion'
rem environment variable.
rem We need the shaveVersion.mel script so let's make sure it exists.
if not exist scripts\shaveVersion.mel goto noFile
find "return" <scripts\shaveVersion.mel > version.dat
set /p shaveVersion=<version.dat
del version.dat
rem
rem Note that because of the recursive nature of these assignments
rem (i.e. shaveVersion is being defined in terms of shaveVersion)
rem they will not work inside an 'if cond (...) else (...)' construct
rem because Windows treats that as a single statement and does variable
rem substitution once, when the statement is read in, not as each
rem statement is executed. So we have to use the 'if cond goto' construct
rem instead.
rem
set shaveVersion=%shaveVersion:return=%
set shaveVersion=%shaveVersion:"=%
set shaveVersion=%shaveVersion:;=%
set shaveVersion=%shaveVersion: =%
set shaveVersion=%shaveVersion: =%
set result=0
goto done
:noFile
echo Error: cannot find scripts\shaveVersion.mel. Build terminated.
