+# Disclaimer: Though I am an astronomer at the Jet Propulsion Laboratory, this
+# package was prepared on my own time on my own machine. Neither the United
+# States government, the National Aeronautics and Space Administration, the
+# California Institute of Technology, the American Astronomical Society, nor
+# the Jet Propulsion Laboratory endorse this package - indeed, they probably
+# don't even know of it's existence. Use of this package is covered by the LyX
+# license which is found in the file COPYING in the root directory of the LyX
+# distribution.
+#
+# Version 0.0 5/27/99 - Initial submission, basic LaTeX equivalents
+# Version 0.1 6/04/99 - Most everything in sections 2.1-2.11 of AASTeX guide
+# works. References work with some ERT. Regular tables
+# (2.14) okay, deluxetable will never be supported.
+# Figures (2.13) not even attempted yet. Misc (2.15)
+# partially supported, but much will remain ERT.
+# Style options (section 3) can be typed into Extra
+# Document options.
+# Much cleaning of this file needs to be done.
+# Version 1.0 6/09/99 - Implemented remaining commands as well as possible.
+# There is little more I can do unless LyX source code
+# is changed. (Not by me!) Documentation, template, and
+# example files are available.
+# Version 1.1 7/25/99 - Changed \url to take advantage of new layout option.
+# Version 1.2 4/18/02 - Updated for natbib in 1.2.0
+# Version 1.3 5/7/04 - Updated for AASTeX 5.2
+# Version 1.4 26/10/08 - new custom insets for \altaffilmark, \tablenotemark
+# - new environments for \altaffiltext and \tablenotetext
+# Version 1.5 26/11/12 - added mandatory argument for \altaffiltext
+# Version 1.6 23/01/15 - fix for the optional argument of \figcaption
+#
+# Version 6.0 31/03/16 - Stub for AASTeX 6.0:
+# new layout file aastex6.layout, because
+# aastex.cls was renamed to aastex6.cls (2016/02/16)
+# (cf. LyX ticket #10027)
+#
+# Version 6.2 14/08/18 - Stub for AASTeX 6.2:
+# new layout file aastex62.layout, because
+# aastex6.cls was renamed to aastex62.cls (2017/10/16)
+#
+# Version 6.3 04/03/24 - Stub for AASTeX 6.31:
+# new layout file aastex631.layout, because
+# aastex62.cls was renamed to aastex631.cls (2021/09/16)
+##
+# TODO: - support for new commands (see below)
+# - aastex6.cls loads hyperref (with pre-set options) and url
+# -> option clash if "Use Hyerref" is selected in Document>Settings
+# support for new commands in aastex 6.3 and aastex 6.31 versions
+# string freeze for lyx-2.4.0, must be done for lyx-2.4.1
