Interesting and useful tool. I'm sure many sysadmins have
created such tools for their own needs, but it wouldn't be
bad to have one publically available from the ports collection.

In order to employ an alternate password generation program
(e. g. pwgen), you could even add an entry to your configuration

Style is highly debatable and is discussed ocassionally on this
list. But finally, YOU are the programmer and YOU are the one
who decides about style.

Programming tips to mainly rely on which programming language
you use. For example, if you're using C, I would suggest you to
only use "safe functions" (e. g. no strcpy() function) and
always check return values (e. g. fopen(), fputs() and fclose()
functions, if you use them for accessing files). In case you
are using threads, check that your program is "thread safe".

Testing as much as possible is important because you're writing
a program that is acting on system level (root) when it does
"simply" create user accounts.

In order to comply to FreeBSD's philosophy of quality, you should,
if your program is complete, take the time to write a manpage.
As a developer, I always loved FreeBSD for its excellent
documentation. Don't do it "the Linux way" - leave documentation
to the Web, a Wiki, or the users. :-)
