# `re` does a repack of an sfx which you already executed once
|
||||
# (grabs files from the sfx-created tempdir), overrides `clean`
|
||||
#
|
||||
# `gz` creates a gzip-compressed python sfx instead of bzip2
|
||||
#
|
||||
# `lang` limits which languages/translations to include,
|
||||
# for example `lang eng` or `lang eng|nor`

# compression tweaks:
|
||||
#
|
||||
# `gz` creates a gzip-compressed python sfx instead of bzip2
|
||||
# (improves compat with minimal and/or ancient pythons)
|
||||
#
|
||||
# `gzz 50` uses zopfli to create a gzip-compressed python sfx
|
||||
# (better compression than regular gz without affecting compat)
|
||||
#
|
||||
# `xz` creates an xz-compressed python sfx instead of bzip2
|
||||
# (tiny bit smaller, but needs modern python to run)
|
||||
#
|
||||
# `nopk` disables js/css compression; builds faster, and
|
||||
# the sfx becomes smaller, but reduces runtime performance
|
||||
#
|
||||
# `udep` unpacks compressed js/css (use with `nopk` and `xz`);
|
||||
# even smaller sfx, much worse RAM/network waste at runtime
|
||||
# (only useful for jokes such as putting the sfx on a floppy)
|
||||
#
|
||||
# _____________________________________________________________________
|
||||
# core features:
|
||||
#
|
||||
# `no-ftp` saves ~30k by removing the ftp server, disabling --ftp
