On the beginning of Configure perl program, there is a statment as follows:
: eval 'exec perl -S $0 ${1+"$@"}' if $running_under_some_shell; ## ## Configure -- OpenSSL source tree configuration script ## Could someone help to explain? I can not find the means of the symbol ":" at the beginning of perl program and the variable $running_under_some_shell.
