:by hand: adv. 1. Said of an operation (especially a repetitive,
trivial, and/or tedious one) that ought to be performed
automatically by the computer, but which a hacker instead has to
step tediously through. "My mailer doesn't have a command to
include the text of the message I'm replying to, so I have to do it
by hand." This does not necessarily mean the speaker has to
retype a copy of the message; it might refer to, say, dropping into
a subshell from the mailer, making a copy of one's mailbox
file, reading that into an editor, locating the top and bottom of
the message in question, deleting the rest of the file, inserting
`>' characters on each line, writing the file, leaving the editor,
returning to the mailer, reading the file in, and later remembering
to delete the file. Compare {eyeball search}. 2. By extension,
writing code which does something in an explicit or low-level way
for which a presupplied library routine ought to have been
available. "This cretinous B-tree library doesn't supply a decent
iterator, so I'm having to walk the trees by hand."
