28 # this script cannot handle figuring out where it lives, so approaches that
29 # get the THISDIR will fail. this is a consequence of this always being used
30 # in bash's 'source' directive, which does not pass the script name as
31 # argument 0. instead, we just check for the bad condition of a malconfigured
32 # script system and try to repair it.

51 The feisty meow configuration is damaged somehow. Please change to the
52 directory where it is stored, e.g.:
54 cd /opt/feistymeow.org/feisty_meow
56 and run this command (the whole unwieldy multiple line chunk inside the bars):
60 exec bash -i 3<<EOF 4<&0 <&3
61 echo -e '\n\n^^^ errors above here indicate potential problems in .bashrc ^^^';
62 export FEISTY_MEOW_APEX=\"\$(pwd)\"; export FEISTY_MEOW_SCRIPTS=\$FEISTY_MEOW_APEX/scripts;
63 export FEISTY_MEOW_SHOW_LAUNCH_GREETING=yes;
64 /bin/bash \$(pwd)/scripts/core/reconfigure_feisty_meow.sh;
65 source \$(pwd)/scripts/core/launch_feisty_meow.sh; exec 3>&- <&4
70 This code snippet assumes that the .bashrc file could still need editing to
71 fix an erroneous FEISTY_MEOW_APEX variable, so we skip it above when bash
72 runs. Check \$HOME/.bashrc to see if a change there will fix the problem.
