*: HUUUGE changes animia has been renamed to animone, so instead of thinking of a health condition, you think of a beautiful flower :) I've also edited some of the code for animone, but I have no idea if it even works or not because I don't have a mac or windows machine lying around. whoops! ... anyway, all of the changes divergent from Anisthesia are now licensed under BSD. it's possible that I could even rewrite most of the code to where I don't even have to keep the MIT license, but that's thinking too far into the future I've been slacking off on implementing the anime seasons page, mostly out of laziness. I think I'd have to create another db file specifically for the seasons anyway, this code is being pushed *primarily* because the hard drive it's on is failing! yay :)

5 # SYNOPSIS
6 #
7 # AX_HAVE_QT
8 #
9 # DESCRIPTION
10 #
11 # Searches $PATH and queries qmake for Qt include files, libraries and Qt
12 # binary utilities. The macro only supports Qt5 or later.
13 #
14 # The following shell variable is set to either "yes" or "no":
15 #
16 # have_qt
17 #
18 # Additionally, the following variables are exported:
19 #
20 # QT_CXXFLAGS
21 # QT_LIBS
22 # QT_MOC
23 # QT_UIC
24 # QT_RCC
25 # QT_LRELEASE
26 # QT_LUPDATE
27 # QT_DIR
28 # QMAKE
29 #
30 # which respectively contain an "-I" flag pointing to the Qt include
31 # directory, link flags necessary to link with Qt and X, the full path to
32 # the meta object compiler and the user interface compiler both, and
33 # finally the variable QTDIR as Qt likes to see it defined.
34 #
35 # Example lines for Makefile.in:
36 #
37 # CXXFLAGS = @QT_CXXFLAGS@
38 # MOC = @QT_MOC@
39 #
40 # After the variables have been set, a trial compile and link is performed
41 # to check the correct functioning of the meta object compiler. This test
42 # may fail when the different detected elements stem from different
43 # releases of the Qt framework. In that case, an error message is emitted
44 # and configure stops.
45 #
46 # No common variables such as $LIBS or $CFLAGS are polluted.
