+generally useful commands
+=========================
+
+ pwd:
+ reports similarly to the good old system "pwd", but translates the $HOME
+ variable into the '~' name. e.g., if you're fred in /home/fred/turnips
+ and you run 'pwd', then it will print: ~/turnips
+
+ i:
+ take inventory. prints out some time and relative dimension in space
+ information and shows the current directory's contents.
+
+ dir or l (lower-case L):
+ show the directory with a "summing" feature that calculates the full size
+ consumed by all files in the listing, with somewhat esthetic output.
+
+ ll:
+ like 'dir' but also includes hidden files (e.g. those starting with a dot).
+
+ ls:
+ the standard ls command (not the summing directory), but with ls colors
+ enabled.
+
+ del or rm:
+ invoke "safedel" feature to remove the files specified. this archives the
+ deleted files in "$TMP/zz_safedel_keep" and writes a report of the deletion
+ history in "$TMP/zz_safedel_report.txt".
+
+ note about safe deletion support:
+ currently there is no "empty the trash" function aside from running a
+ command such as:
+ $ \rm -rf $TMP/zz_safedel*
+ the backslash forces bash to run the "rm" tool from the path rather than
+ using the feisty meow alias. a trash flushing feature is planned for the
+ somewhat near future.
+
+ regenerate:
+ runs the feisty meow reconfiguration process to adapt to a new version of
+ the scripts. this also updates the current shell's functions and aliases
+ to reflect any changes.
+
+ get_feisty:
+ update the feisty meow codebase from its origin and run the regeneration
+ script to update the current user's feisty meow configuration.
