A lot of software uses incorrect locations for script interpreters, most notably /usr/bin/perl and /bin/bash. This fixes shebang lines in scripts listed in SHEBANG_FILES. Currently Bash, Java, Ksh, Perl, PHP, Python, Ruby, Tcl, and Tk are supported by default. To support another interpreter, set SHEBANG_LANG, lua_OLD_CMD and lua_CMD. For example SHEBANG_LANG=lua, then lua_OLD_CMD=/usr/bin/lua and lua_CMD=${LOCALBASE}/bin/lua.
