In addition to this, PCI produces a number of software packages that are available as freeware, or as demo versions, to which anyone is welcome.

The directory /pub/incoming is available for users to upload things they wish to make available to other PCI users (and the world in general). There are a number of restrictions on incoming files:

• All files placed in /pub/incoming are subject to approval by PCI and once approved, will be moved to the general /pub directory (or an appropriate subdirectory). Until approved, they will not be accessible.

• Only files and programs relating to PCI software and/or Remote Sensing / Image Analysis will be accepted. General purpose ftp sites exist for other software and files.

• No executable or object code will be accepted. There are no exceptions to this rule. If you want to make something available to other users, send it as source. If necessary PCI will build it for the various system(s) it supports.

• PCI is very international in nature, as is the Internet. Please keep in mind that anything uploaded to PCI will become accessible to the entire world - PCI maintains no geographic restrictions on access to its ftp server.

• Do not upload anything anything non-distributable, or of even questionable legality.
