Commands:
2rows Print the contents of first and last row in each sheet
3rows Print the contents of first, second and last row in each sheet
bench Same as "show", but doesn't print -- for profiling
biff_count[1] Print a count of each type of BIFF record in the file
biff_dump[1] Print a dump (char and hex) of the BIFF records in the file
fonts hdr + print a dump of all font objects
hdr Mini-overview of file (no per-sheet information)
hotshot Do a hotshot profile run e.g. ... -f1 hotshot bench bigfile*.xls
labels Dump of sheet.col_label_ranges and ...row... for each sheet
name_dump Dump of each object in book.name_obj_list
names Print brief information for each NAME record
ov Overview of file
profile Like "hotshot", but uses cProfile
show Print the contents of all rows in each sheet
version[0] Print versions of xlrd and Python and exit
xfc Print "XF counts" and cell-type counts -- see code for details
[0] means no file arg
[1] means only one file arg i.e. no glob.glob pattern
