description         TeXDist directory structure for MacPorts' TeX Live
long_description    ${description}. \
                    It is used by MacTeX's texdist utility and TeX \
                    Distribution Preference Pane to switch between TeX \
                    distributions. \
                    \nSee /Library/TeX/Distributions/TeXDist-description.rtf \
                    (also distributed with MacTeX).

# The directories MacPorts-TeXLive.texdist and MacPorts-teTeX.texdist in
# /Library/TeX/Distributions/ and MacPorts-TeXLive and MacPorts-teTeX in
# /Library/TeX/Distributions/.FactoryDefaults/ are considered by
# TeX Live / MacTeX developers as owned by MacPorts.
#
# From a private email exchange with Richard Koch:
#
#    "Do you have direct contact with the MacPorts people. If so, you
#     might propose that
#     [...]
#     b) From now on, they install the data structure themselves.
#     Surely b) is the correct option, and I follow it for all distributions
#     except Fink-tetex, MacPorts-teTeX, and MacPorts-TeXLive."
#
#    "> I'm willing to help improving this (e.g. I could prepare a port
#     > for the data structure in MacPorts), [...]
#     AHA. Then it is great that you wrote. Go ahead and write your own data,
#     and reuse the names I used, because then MacTeX will not overwrite it."
#
#    "From now on, these entries will not be created by MacTeX. If the
#     entries already exist, either because we wrote them or because you
#     changed them, MacTeX won't change them. If you remove the entries
#     entirely, then new versions of MacTeX won't add them back, but the
#     rare use of old install packages will."
#
# Moreover, they are useful only if MacPorts' TeX Live is installed, so
# removing the old ones here and not restoring them in post-deactivate
# does no harm to the user. Consider also that teTeX does not exist
# anymore in MacPorts.
