+generally useful commands
+=========================
+
+ pwd:
+ reports similarly to the good old system "pwd", but translates the $HOME
+ variable into the '~' name. e.g., if you're fred in /home/fred/turnips
+ and you run 'pwd', then it will print: ~/turnips
+
+ i:
+ take inventory. prints out some time and relative dimension in space
+ information and shows the current directory's contents.
+
+ dir / l:
+ show the directory with a "summing" feature that calculates the full size
+ consumed by all files in the listing, with somewhat esthetic output.
+
+ ls:
+ the standard ls command (not the summing directory), but with ls colors
+ enabled.
+
+ del / rm:
+ invoke "safedel" feature to remove the files specified. this archives the
+ deleted files in "$TMP/zz_safedel_keep" and writes a report of the deletion
+ history in "$TMP/zz_safedel_report.txt".
+
+note: 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 from
+the feisty meow alias.
+a trash flushing feature is planned for the somewhat near future.
