# Usage: to be invoked from .bashrc.
# i.e., add at the end of .bashrc:
# [ -f "$HOME/.bashrc.$USER" ] && . "$HOME/.bashrc.$USER"
#
# Debian default ~/.profile usually does:
# 1) source .bashrc if it exists
# 2) add "$HOME"/bin in PATH

# Better to have a ~/.bash_profile with the lines above.
# _var_del() - remove an element from a colon-separated list.
# $1: name (reference) of a colon separated list
# $2: element to remove (string)
#
# _var_del() removes every occurrence of $2, if there are more than 1,
# and leaves $1 unchanged if $2 is not present.
#
# Example:
# With VAR's value being "foo:bar:quax:bar". Using "_var_del VAR bar" will
# leave VAR with the value "foo:quax".

# _var_prepend() - prepend element to colon-separated variable.
# $1: variable name (reference)
# $2: element to add (string)
#
# Any occurrence of $2 in $1 is first removed, then $2 is added at $1 beginning.

# Example:
# With VAR's value being "foo:bar:quax:bar". Using "_var_prepend VAR bar"
# will leave VAR with the value "bar:foo:quax".
