# Completion options
#
# These completion tuning parameters change the default behavior of bash_completion:
#
# Define to access remotely checked-out files over passwordless ssh for CVS
COMP_CVS_REMOTE=1
#
# Define to avoid stripping description in --option=description of './configure --help'
COMP_CONFIGURE_HINTS=1
#
# Define to avoid flattening internal contents of tar files
COMP_TAR_INTERNAL_PATHS=1
#
# Uncomment to turn on programmable completion enhancements.
# Any completions you add in ~/.bash_completion are sourced last.

# Aliases
#
# Some people use a different file for aliases
# if [ -f "${HOME}/.bash_aliases" ]; then
#   source "${HOME}/.bash_aliases"
# fi
#
# Some example alias instructions
# If these are enabled they will be used instead of any instructions
# they may mask.  For example, alias rm='rm -i' will mask the rm
# application.  To override the alias instruction use a \ before, ie
# \rm will call the real rm not the alias.
#
# Interactive operation...
