moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
Scripts that are meant to be run in the calling shell: Fixed bug where running the script inside another script would make the script think it was being run as a program, and abort with a usage error
Scripts that are meant to be run in the calling shell: Fixed bug where running the script as a program (without initial ".") wouldn't be able to call return in something that was not a function. Converted all code to a <script_name>_main method so that return would work properly again. Converted all variables to local variables.
env_password: return instead of exit if password not yet stored, in case user is running it from a shell without the initial "-" argument. (This would be the case if the user is just testing out the script, instead of using a command that env_password directs them to run.)
env_password: Use ${BASH_SOURCE0} for $self and $self for $0. return instead of exit on usage error in case user is running it from a shell.
env_password: Print Usage message if run without initial "."
env_password: Fixed to set the environment variable in the calling shell. Do this by cc-ing the tty only on messages before the "Enter password" prompt, because the redirect creates a subshell which causes the env var to only be set within that subshell.
env_password: Fixed bug where exit command would not cause it to exit, because pipefail shell option was not set. Moved automatic exiting of the calling script into env_password itself.
env_password: cc stderr if it's a log file
env_password: Print all messages to /dev/tty so the user sees them even if stderr is redirected to a log file. Exit if password not already set, because e.g. scripts run in the background will not be able to prompt for it.
env_password: Allow user to change saved password
env_password: Don't print instructions for storing password for the session if called to store password for the session
env_password: Print absolute path to env_password in case invoking script changed the working directory
env_password: Print instructions for storing password for the session
Renamed util to bin
Moved everything in scripts to root. inputs_Makefile: Don't run "all" when installing.
env_password: Added optional message arg
env_password: Print Usage message to stderr
Converted scripts back to bash that required bash-specific features
Added support for multiple database engines. Changed SALVIAS_db input to use user-entered password.
