Package: busybox
Version: v1.25.1
Severity: wishlist
The attached patch lets the user configure the command used to format man pages
by busybox's man.
I'm using heirloom-doctools instead of groff in a toy distro, which doesn't
provide gtbl (just tbl) and doesn't work with -Tascii (I use -Tutf8 instead),
so I am using this to let me view man pages.
I think that it would also be useful if busybox was built without seamless
decompression - the command could pipe the man page through gunzip before
sending it on.
I've tested this by building with the defaults, with a changed command, and
without man.
Regards,
Alastair Hughes

Subject: [PATCH] man: let the user specify the format command
Let the user configure the command used by man to format man pages. Not
all systems provide gtbl, for instance, and if man is built without
seamless decompression compressed man pages should be piped through an
external gunzip.
