/*
|
||
|
|
* This file is responsible for defining two operations that are not
|
||
|
|
* directly portable between Unix-like systems and Windows NT, option
|
||
|
|
* parsing and directory scanning. It is here because it was decided
|
||
|
|
* that the "gen" build utility was not to depend on libisc.a, so
|
||
|
|
* the functions delcared in isc/commandline.h and isc/dir.h could not
|
||
|
|
* be used.
|
||
|
|
*
|
||
|
|
* The commandline stuff is really just a wrapper around getopt().
|
||
|
|
* The dir stuff was shrunk to fit the needs of gen.c.
