From MorphOS Library
From the original xadmaster.library manual:
XAD2LhA - extracts data from other archives and stores it in an LhA archive
FROM/A, TO, PASSWORD/K, NE=NOEXTERN/S, QUIET/S, HEADER0/S
FROM - specifies the file archive that should be handled. TO - is the name of destination lha file. When not specified, the source name extensions are stripped and .lha is added. PASSWORD - can be used to supply a password for unarchiving of encrypted archives. This argument requires the keyword PASSWORD. NOEXTERN - prohibits the use of external clients for recognition purposes. HEADER0 - uses header level 0. This header is older and does not have special information. QUIET - option makes the program really silent.
Shell> xad2lha archive.tar Make an lha archive from tar archive. Shell> xad2lha archive.lha archive2.lha Recreate the lha archive.
