1159# @USAGE: <file on cd1> [file on cd2] [file on cd3] [...]
1160# @DESCRIPTION:
1161# Aquire cd(s) for those lovely cd-based emerges. Yes, this violates
1162# the whole 'non-interactive' policy, but damnit I want CD support !
1163#
1164# With these cdrom functions we handle all the user interaction and
1165# standardize everything. All you have to do is call cdrom_get_cds()
1166# and when the function returns, you can assume that the cd has been
1167# found at CDROM_ROOT.
1168#
1169# The function will attempt to locate a cd based upon a file that is on
1170# the cd. The more files you give this function, the more cds
1171# the cdrom functions will handle.
1172#
1173# Normally the cdrom functions will refer to the cds as 'cd #1', 'cd #2',
1174# etc... If you want to give the cds better names, then just export
1175# the appropriate CDROM_NAME variable before calling cdrom_get_cds().
1176# Use CDROM_NAME for one cd, or CDROM_NAME_# for multiple cds. You can
1177# also use the CDROM_NAME_SET bash array.
1178#
1179# For those multi cd ebuilds, see the cdrom_load_next_cd() function.
