- When -pn has been passed (i.e., the user wants the 'apt-get install'
step to be skipped), don't waste time checking the available
dependencies. Rationale: someone using -pn has probably already
installed the required packages either manually or during a previous
run of download_and_compile.sh, and anything missing couldn't be fixed
under -pn regime anyway, by definition. Assume that users passing -pn
want to build with the packages they already have, and let them spare
some time and CPU cycles.
- New options --package-manager and --sudo. The former defaults to
'apt-get' as usual, but 'aptitude' can be used as well. The --sudo
option specifies the sudo-like program to use. Passing --sudo=echo
allows one to see the apt-get or aptitude commands without running
them. Passing --sudo= or --sudo="" (i.e., giving an empty value)
causes the package manager to be called directly, without any
intermediate sudo-like program.
- The PKG variable is now a Bash array, which is a bit cleaner and
blends better with the new, array-based implementations of
_aptUpdate() and _aptInstall() (whose purpose is to allow the
newly-added flexibility without multiplying the code paths).
